It looks great. I do have a couple of suggestions. The book looks kind of odd open that way. Is there any way to have the part not propped up by the closed book laying flat on the ground? Also, perhaps you should try using opacity instead of color dodge on the fairy as an experiment. Dodge makes the fairy look superimposted on some parts of the woman's body, and I am not sure that's the effect you are going for. You might want to attack the crease of the main woman's armpit with a touch of postwork. I always have to fix poser armpits after a render to make it look a bit less plastic. I really like the composition. It's a great image.
