A nice picture of a very sweet girl. The light here is very warm, and her hair and cheeks are lit up. IMO, using a warmly colored background in this light rather than the neutral-cool green-gray would have enhanced this picture tremendously. Also the focus on the eyes could be a little sharper. I'd also try a tighter crop from the top and right.
Great lighting on this one....but the skin tones are a little too red and the hair a tad too yellow, but I realize this may just be my personal preference. Still a good pose and pleasant overall feel.
