The first thing I noticed in this work is the shading and the delicate contrast between light and dark. I think it was done very very well. I thought her hair was done nicely as well. I like the way her hands were done.

If I had any critique to give at all- which isnt really a critique, more of a suggestion- is to clean up the lining so we can see how gorgeous her contours are ^_^ Then again, it looks great as is, so dont even listen to me hehe.

Thanks for sharing =)
