Her expression is great. It seems a little sassy yet still serious at the same time. The image would benefit greatly from shading since everything else looks good.

I love the eyes. They're very expressive. The pose is so sassy. What did you use to color it? It looks so soft.

The only thing I would say is maybe a bit of shading. Shading can be sorta a twit though and mess it up more...on second thought, I like it the way it is. Nice work
