This is a great job, and the model's pose is way hot sexy! as Fat B****** would say... I really like the way you did the seams, and the wrinkles are just enough for my taste. I would have added some shadow seperation to the edges of the green part of her costume, though, and especially around her neck. but you got he hair streak just right.
Great job. My only technical critique would be that parts of teh costume look a little splotchy. Using a low level smudge or blur will fix this. I could be wrong, but It looks like you work the same way I do, adjusting the hue/saturation of layers, rather than airbrushing them. This sometimes results in the splotchiness, if the model has inconsistent skin tone or you are working off of a low res base pic.
