Nice try! This shot would have worked better if the model was further to the left (as I look at it) giving more story on the right, and keeping the viewer focused in a specific area. As is, the eyes wander from left to right around her. Again, flat lighting as a result of shooting in midday sun.
Here I think you have a picture that isnt so great, but if you looked further you would have something very worthwhile. Might you try opening this image, zooming in and cropping just around the eyes, showing your reflection in the beach itself. good luck.
I don't want to be negative, because the girl is pretty etc...but this is nothing more than a snapshot really and the reflection of the photographer in the glasses is distracting...as is the background...you may want to try a different perspective, take a shot from overhead as she's lying there? Not sure, but this is like a quick snapshot and doesn't have originality about it...sorry, just want to help you improve
