I constantly get bored at school, so I draw a lot. These are a couple of pictures I've drawn in the last few months. I guess I want some opinions and constructive critism on how I can improve? By the way, the main reason I haven't shaded or colored is because I'm waiting till I get a tablet to try.
I'm out of paper right now (I should get some within the next week), but I'll be happy to draw your avi! I'm part of a joint art shop, so I guess I should post the link if you have any questions.
