Chair

Oh man, I know that there are lots of problems with this piece, but I decided to submit it anyway. It's been a while, and for the most part, I have a lot of half-finished pieces sitting on my desk that I could submit but haven't yet.

I tried varying line weight to give depth to the piece, which didn't really work because I sketch too roughly. Advice?

Either way, enjoy!

Edit: I fixed the shading under her body and on the chair legs. Is it better now?
