Good stuff agent, although I feel it would be better if you replaced the orange skin tone with that grey tone for all the flesh areas. The two contrast too much without any apparent light source so it tends to confuse the line of her body. As Boz said the black is very overpowering, as a general rule, like in painting, pure black should be avoided, its just too er...black...its flat, even a dark grey would give it a warm look rather than just a void. Hope that makes sense
The same goes for pure white, its just too intense and the brain confuses it as a space in the canvas, take my last posted piece for example, the 'white' t-shirt actually has a slight cream tone to it.
Couple of pointers in general for people:
- Dont use professional model photos, they are generally fairly low res and will force you to work small, lowering the quality and the ability to work in detail.
If you have a high res photo, like most good stock sites provide, you are able to work at a high resolution and add more points to a curve making them looking smoother when the image is down sized for viewing.
