nudes (can be disturbing or 'challenging') thinker

Working with constraints of an improvised on the spot "studio," I had to live with both wrinkles on the backdrop (bed sheets) and model's physical proximity to it (tiny room). Within the realm of these limitations, what could I have done differently?

My aim was to present the model in the most neutral fashion; to understand what I mean, please see my critique request for this picture and/or check out the other pictures in this folder.

The grain feeling is more and specially, I like to be a little bit to adjust the son darkly recently, feeling that the lighting has a little the interference view, personal opinion, make the reference only.

Free see my picture, please criticize much.
