I think it's a beautiful portrait and like Julian, the simplicity really suits the subject. As banding has been mentioned, may I ask how people deal with it? Before I moved to full PS and 16 bit, I suffered with some banding in the (cloudy) sky on my trip to Yorkshire. I tried to retouch and for the most part it worked, but I found it really difficult to shift. The heal tool seemed to carry the pattern over. In the end I think I cloned 30% from here and 50% from there until it blended away, but I still have nightmares about finding it again...
