The backround doesn't suit the rest of the shot, and her hands look too posed and placed and manicured. Unatural looking. I love the black makeup and the black flowers. If it wasn't for those two things, I wouldn't have even looked at this shot.
Now this is stunning. To be honest, I love this more than a majority of your other work. Her eyes and expression is so soft and it really works well with her hands, which are really graceful. The only think I don't like about this photo is how awkward looking her right hand is. Compared to her forearm, the hand is rather small. But that isn't anything too major. The photo is still great, and the contrast between her hair and the black flowers is beautiful. I'm definately adding this to my favourites.
