Ah! This is good. The contrast on the lips and the cool dark skin are a bit overwhelming, so maybe calming the color down, (darker). The shading overall is good, but the collar bone shading just seems like it could be smoothened out more, and the hand is a bit too round, almost like a glove blown up, ya'h no? The thumb should start at the end of the hand. Add more to the background too. I like this though. There a lot of good things in it, too.
