I like the angle -- it makes the shot anonymous and voyueristic at the same time. However, I think minor details like the upper right corner, the dark fold in the bed cover near her head and dark flower petal shap (shadow ?) coming in from the left side at her knee could be xleaned up. Her forehead looks very detailess...did you blur it? Points along the hairline are blurred and points appear sharper, making me think there was post on the face. Her hair (which is closer) has good detail and skin on her far hand has more detail (which is further). Lack of detail in the middle means a) it wasn't there to begin with, or b) you may want to back off the adjustment a bit.
Your original is much cleaner than the posted image looks ... the compression got you. RFS has a post showing more detail, but in essence, post a link to your image without the "/large" directory in it.
Thanks for the post!
