Awesome composition! Looks like a fabulous evening! I can almost smell the water. Only thing I would have tried different would be to face the model into the sun so that you can see more of her face.

Great lighting on this portrait and a strong composition. Something I can't put my finger on is whether her face is too small of an element in this or maybe a little too obscured. But that's just my opinion creeping in, this is a very nice photo, period.
I like the light on the girls hair and the movement of her body goes well with the movement in the 'grass' behind. the softness works well in this image :o)
