This is looking freakin' awesome so far! You already pointed out her foreshortened arm, sooo....I might be wrong, but I feel the leg closest to us is just a little bit too big. In the least, I think her ankle is slightly too thick...but I again, I could be wrong.
I really like the color scheme.
And I have to say I'm in love with your current Icon/Avatar, which is totally off subject.
