Ow, a book? Interesting. I think a few edits to this will be great. You need to make her bone structure more human like. You've missed out the jaw, from the chin. The angle should never be that sharp. You need to make the corner of the jaw line aligned to the mouth in this view. If you move the jaw down, it will certainly look better. Since the face is supposed to be the main attraction of the whole picture, these little things really makes a difference. The collar bone too, you've missed that out too so it makes her boobs look really awkward being like that.

waaa...,the color is soft. i like to see that

The drawing this good, but for my has two great fayos (that I not to be perhaps made it more good) first are the chin, and the second that I see is that the leg that this but close is but small that the other, when it would the other way around have to be and as soon as to notice, and soon this that the grip of the sword has a ridiculous size
