Mmmmm.... gorgeous! Love the light and colors. And her pose and expression are so playful and carefree as to bring a smile to my face just by looking. A lovely image!
Lovely smile and pose. Great lighting. Maybe you could crop tighter to her and lose the foot, which I found my eye drawn to more than was probably intended.
Beautiful shot, great use of the DOF. The only thing bothering me is the fill light (flash or reflector) is too intense, I would have reduced it a bit, maybe by 2/3 stop.
