NIIIIIICE. I love how you did her face. And the shading on her hair. COOL.

You've captured the style of the Batman animated series well here. I like the expression, it's very telling, as is the pose. Good hands come with lots and lots of practice and looking from life, but the one here isn't bad. The lines on the undersides of her arms go a little high up her body, though, and almost look detached from it. But that's more a personal preference. Nice work regardless.
