This is obviously just stunning work, it's a shame you haven't got more portrait work in your gallery because this is really exceptional. It's so unlike, and so much more... deep than other smiling portraits. You caught an actual moment, and perhaps it was posed, however - it doesn't seem that way at all. Her facial expression is natural, her eyes are unbelievabley gorgeous and her hair is thee most beautiful colour
I love how you've included thirds into your composition here with regards to her face and actual skin.
Amazing, my friend.
