this is composed nicely and seems to be an original idea, shot is a little dark, not sure if shot would be recognized as silence w/wo title--(waves, gulls,wind)
I like aspects of this image - the texture within the sand leading us in, the long shadows, the empty beach - but feel that overall it's too dark and that the man is too close to the edge of the frame for a strong composition.
Good idea. Your composition needs some work here. Try putting the man in the lower left of the image so he has somewhere to walk to in the image. Also the image is a little dark.
