I find this a slightly strange yet powerful image. I like its abstractness. For some reason I wish you had not titled it as the title seems to limit the interpretation of this image.
The way the people don't seem to be taking a step really, and are silhouetted, gives a bit of an eerie feel to this. Faceless on the deserted beach, hanging in space.
Quality is a bit rough from what I'd expect of "Fine Art" (but who looks at fine art on a computer anyway?). I can overlook it. The composition is excellent -- the black horizon (or is it water?) in the background, the wooden structure in the front, the shadowy figures -- and the sand which seems to shimmer and shift. Really good.
Very interesting composition. Just a suggestion, but you might crop out the dark line across the top. It pulls the viewer out the the frame and away from the figures and the "good stuff" at the bottom.
