The edge of the lake is bugging me.. I feel like this should be an ocean beach shot with the water as the horizon.
But that's just my predisposition or something..
I'd play up to that tattoo more. It's interesting to me. I think maybe if she were turned a bit towards you and showing it more clearly. I also think a tighter crop sans suit top would be interesting (not saying show her bare chest, keep the crop below that). Maybe with a blue cloudy sky in the background and no ground/lake/horizon..
I don't know..
Also you didn't tell us what your eyes were drawn to, so I don't know if it worked. For me it's the tattoo and hip bones.
