I think the hat looks a little off. It looks like it is part of the head, and it isn't. Next time you draw something similar, keep in mind to draw the hat as a different part. If you did the sides more out it would look better. But that's my opinion. And it looks like you only have one arm, and it looks like you have no feet. The legs are a little short but the body and torso is perfect. The headphones actually look like part of the body as well, so next time make them more off or up, to look like a seperate peice of the body. That's all for that stuff, the good stuff is: I like the blushing parts, and the eyes. The shading is good as well, and I like the circle shadow you put under her too.
1. I agree with the hat XD
2. Of course she only looks like she has 1 hand, she's facing sideways.
3. I purposly made no feet. Can't draw feet nope nope nope.
4. Eh. I guess they could be a bit better.
5. It would be hard to do that because the hat is on top ;=;
Thank's for the tips, I shall try to work on them next time!
