Sounds good.

I think you're stepping in a good direction in terms of a style. The face is looking better and the texture is nice. I think, though, you're concentrating too much on style rather than fundamentals. What I mean by this is that fundamentals is something that all art should abide by (or acknowledge otherwise) while style is more of being different from everyone else.

Your style sticks out compared to others, there's no arguing that at all. If I see yours in a batch of art, I could easily pick yours out. I feel, though, that your art could come even more alive if you try some of the following:

First off, as mentioned in the comments, anatomy is a big thing especially when drawing characters. I do understand you're coming from a more cartoon background, but even cartoons have some form of anatomy (they're just more simplistic looking).

A good example would be Bugs Bunny. Though he does seem rather simple, if you study some different images of him, you see he has the same body proportions throughout and aside from his head being bigger, he otherwise experiences realistic proportions. Now, I do have a cheat sheet on this kind of stuff if you're interested. I got a sketchy one but if you want a reference of quick math tricks to match some anatomy stuff, I'll make a cleaner version for you.

There are cases that cartoons don't abide by normal anatomy (they're cartoons after all), but the key is deliberately disobeying the norm and maintaining that disobedience throughout all pieces you make with the character. Renswick doesn't abide by normal leg length, having an exaggerated length. If you look at the other pictures of Renswick I have, they keep the same extra length.

One thing I do notice is that your head anatomy is much better than before. You used to draw characters with rather large heads, and this one shows a much smaller one. As a tip, here's a shortcut on cartoon height: measure the size of k9's head, from top of the head to the chin. Now, use that to measure how tall she is. From what I'm measuring, she's 4 1/2 to 5 "heads" tall. If you want to keep this head size, make sure you deliberately measure every time to make sure it stays that way. The "realistic" head size is 8 heads tall. I draw characters 6 heads tall.

Now, another fundamental would be angles. Your most recent artwork, "The Blind Vampire" is what I'm talking about. Instead of this forward shot you generally draw characters at (like this one), the Blind Vampire piece shows the character at profile body wise (though the head is turned at the normal angle you always draw in).

What I'm trying to get across is that you have a comfort zone when drawing angles, since you're comfortable drawing at this one normally. I used to have this problem a long time ago. I first only drew characters in profile, then after awhile I only drew them at quarter shots. What you need to do is experiment and get out of your comfort zone. Chances are if you aren't used to it, it's not gonna look pretty. The point is not to be pretty, it's to get more experience in this realm. Prettiness will come later.

Practice drawing your characters at any and all angles. Start off with doing profile shots and back shots. Rotate your character all around and draw them at any and all angles. You got the frontal, now nail the others.

Since you do stick to one angle, your faces are going to look dramatically different in profile. Try sketching faces to begin with in different shots. What you have is a quarter shot (not quite frontal, not quite profile). Try drawing a direct front view (as if k9 was looking straight at us), a profile shot (strictly at the side), and directly from behind her. This will eventually make it far easier to draw her at any angle.

Try different poses, too. I don't mean just having an arm at a different angle. I mean body language. This I only truly got when I was finished with my animation class. Body language in cartoons just sells it. You've drawn some nice expressions before. Now try doing the same, just with the body. Draw the body hunched over/tired/depressed. Draw it upright and ready to take on the world. Draw it in a panic, draw it striking a badass pose. This will make it so just one glance can tell you exactly what a character is feeling/thinking, without even the need of a speech bubble or title.

So, to summarize, you got the style down. It's definitely yours and it does stick out. What you should try out would be anatomy tricks (you can find these on Google or, if you want them, I can make cheat sheets that are easy to glance at and look at the math for body proportions), different angles, and some more body language. I think if you explored these more, your drawings really strike at us with just a glance.

Allow me to say one thing first; This picture shows some amazing improvement over your older work. It's good that you're pushing yourself to improve as an artist, and the effort shows.

Now, on to the critique. Let's start from the top; The coloring on K9's hair is excellent. However, you should try drawing out some more individual strands in the lineart itself, as opposed to just outlining her hair; It would make it flow better. Also, you should to make her ears a little more 3D. Here, they look a bit flat, whereas in actuality fox ears cave inward. It might be helpful to look at some pictures for reference. However, I think that the details on the inside of the ears, while being a small part of the picture, are a very nice touch.

Moving on to the body, the torso area could use a good bit of work. You should define the shoulders more (though not too much; K9 is female, after all), as they slope a bit too sharply downward. Her breasts, on the other hand, could use more of a slope; They're too circular. It would also look quite nice if you put a bit more detail into the shirt, such as wrinkles or creases. As of now, it's a bit flat. The coloring on the shirt (and the pants, as well), comes off as a bit awkward; You should keep in mind that the human figure is made of 3D shapes and forms, and thus, the texture of the clothes should wrap around those shapes and conform to the curves. As for K9's arms, you should try and give them a bit more of a defined shape, making them taper from thick to thin in certain places.

Next up, her hands.... Ahhh, hands. The bane of every artist. I think it would probably be a great help to you to look up reference for hands, or maybe to use your own. The fingers need to have more clearly-defined joints, and the hand should connect to the wrist a little more smoothly. The fur on her right hand cuts off sort of abruptly, and it looks slightly awkward; you should work on making the transition from fur to skin a little more gradual. Detailing the mechanical hand, maybe with little interlocking joints, would help to make it a bit more recognizable, as well.

My critique on her pants is basically the same as it was with her shirt; Wrapping the lines around the figure would make them look much more three-dimensional. The same applies to the cuffs of her pants; You should round them out as opposed to cutting them off with a straight line. Her feet also look a little awkward, as they're not on the same level. You should try drawing out a floor line to help with this, even in pictures without backgrounds. The feet themselves are also in need of detail; Again, looking up reference of a real fox's feet would help with this.

I adore the coloring on her tail, it makes it look very soft and fluffy. However, like her hair, you should work in a few more individual strands in the lineart, for the sake of smoothness.

My final bit of advice is on color scheme; The one you've got here is pretty chaotic and all over the place. You should stick to a limited palette when working with colors. A good maximum for colors is three, though of course, that could change with the character. The colors that you DO use should compliment one another, or fit into the same color category. (i.e. Blue and purple are cool colors, red and orange are hot ones). My recommendation would be to better coordinate K9's outfit to match her hair and her eyes. Maybe some dark blues, or gray.

I hope this has been at least a little helpful to you. : 3 You've come a long way since the first time I looked at your art, and now that you're aiming to improve, things can only get even better. So, good luck! > w <
