Model on beach

I posted this a little bit ago and go no comments on it. I would like

some so if you would please tell me how to improve. Thanks!

The bright sunlit water is a too contrasty background for the dark girl. Her posture looks a bit akward. She doesn't seem to enjoy getting her clothes wet and sand in her hair. The composition isn't balanced, and doesn't lead the eye. Colors are missing the saturated glow of a sunset.

You could try to fix the contrast and colors with digital post processing. Dodge the model and burn the background, but not too much. A scan from the original film might help. Also try playing with different croppings. Maybe you get a chance to reshoot this? Good luck.

is the scan a bad one? The whole image seems kind of dull. Maybe better lighting on the girl as well.
