That's a pretty huge work to me. Originally, the girl is very sexy, charming, and young. However, the piece presents another woman without a complete body. I grew the contour many times, but it's not too hard to work out. The most difficult part is the coloration, especially the face part. I think I spent almost one day. The facial expression seems kind of different from the picture I imitated, but I have no idea to make it better. Thus, here the piece I've done.
