I'm drawing Jennifer Lawrence as Katniss Everdeen (the Hunger Games), though I'm not satisfied with what I've done so far. I'd like someone to point what's missing/wrong in it, so I can improve my drawing.

I'm based on this pic: Katniss Everdeen - Pop on the Pop

My drawing so far: Katniss Everdeen so far on Twitpic

*I haven't yet started adding shades/light effects, I just need help at the shape/details.

It looks very close to me. But I'll ask my sister (obsessed with Hunger Games) when she wakes up

The eyes are wrong.
