From Well, the color isn't too bad. You've got a good understanding of shadows. However, I would highly suggest adding some shades and tones. The image itself looks very reminiscent of a frame from the anime. On one hand that's a good thing because you're coloring is pretty decent. However, one thing you need to note is that animation often cuts corners so often just don't add in tones or shades when animating. Not to mention, the movements and voices in animation are what makes it come to life. However, this is a still image and it would be very much suggested to put shades to make it much more lively. The lines do make it strike out and give more action to the piece, but again it's very limited.Now, the expression is something that I'd also suggest improving. In contrast with the rest of the body, the expression looks very simple and the lines are quite thin. One part that the eyes would focus much on is the face. However, the face really falls flat in comparison to the rest of the body that just has such a boldness and more details. Lastly, the anatomy of the hands is very much off. I know they're supposed to be busted, but in this case the they look naturally out of place than broken.All in all, the image isn't too bad, the line work is decent and some details really fit. I would suggest giving more shades to give more life and to improve the expression. Keep it up!
