DR0ck, Wow what a fantastic shot. I'm not skilled enough to offer true critique, but this is fantastic work. Love the blown-disheviled look of the model's hair. It gives the image a very natural and real look You've captured her eyes amazingly well.
The composition is excellent, inviting the viewer into the intimacy of her comfortable cozy-couch. The choice of lingerie accents her frame well.... although the detail of the lace in her bra seems to be lost in the blackness. I struggle with getting the details of black lingerie and "little black dresses".. can't ever seem to get them to show up well.
My only critique would be that the color of her eyes seems to be over brightened. But that's more of a personal taste issue.
Kudos on a fantastic image. Wish I could get such rich colors and detail! You've almost made me consider shooting Canon over Nikon.
