>>1 Her chest looks entirely too large for her shoulders, and she's too... curvy. Curves are nice, but you have to know how to do them right. There are certain dips and such in a woman's body that you need to know if you're going to draw them half-clothed. Also, while I normally wouldn't suggest putting certain details in, I think you need to for it to comply with the rest of her costume. The panties should have some folds in them to make them look natural. The body has a lot of empty space, as well. You made these beautiful patterns on her clothing/weapons, but her body has nothing else.
You drew the hands and feet exceptionally well. In the arms, the notch in the elbow isn't thick enough, and you forgot the bump and following indent right before the hand. The thumb also looks a little strange. I understand the line you were trying to do, but it looks a little off. The face and hair are absolutely stunning.
With a little work, you could be a great artist. Keep going at it. However, please post more art in this thread. If you don't intend to make this your personal art thread, delete the first post and move the picture to the art sharing thread. We don't need a thread for a single picture ;O
