Wow! This is a stunning portrait. Very nicely done. Looks like a headshot for a magazine cover. I like how you've included just enough background to get some effective bokeh working as highlights and contextual setting.
I have come back to this one three times now. It's not the most perfect lighting, but the composition is so spot on, and her smile is so authentic - it's nearly a perfect portrait.
What a very pretty portrait of a very pretty girl. I love the way her hair is blowing and you can see the freckles on her skin, nice catch light in her eyes as well. 9
