MIssed this post until 9:32 PM tonight. I like her expression, and as Tuirediron mentuoned, she is lovely and has a pleasant expression. I think a little bit more of a tighter crop (some removed from the left hand side) could also work nicely on this shot.
It's a good shot. Agree with what has been said so far. For me the lighting was a bit flat and the background has already been covered. I would agree with that. Rather busy. My lighting thing though is primarily a personal thing.
