Thank you all for your comments, I'll be working on improving this piece, and especially focus on the recurring critiques regarding her arms and her head.
@Mirm: Err, shoe size? Well, she's supposed to be rather tall for a woman (5'10'' or so), but her feet aren't particularly big.

- Tiny head, big legs

+ Nice colors, freckles ^^

 Mirm is right, her arms are too skinny, but i think her legs are fine. 

Is it a 4-handed sword?

I think her arms too small and legs too big. What's her shoe size?

 Quite a large sword, and quite a tiny head. The pixelling is pretty good, a less diffuse light source might make for more believable volumes and a more interesting image.
