Hello Shadow,
I would have perfered to have seen, at least part of the real you in some way. I think you cropped a little too much at the top, and the light spot in the center distracts. The footsteps in the sand make a nice backdrop.
Would like to have seen some actual person here, but hey, counts as a self portrait in my opinion. It doesn't really appeal much to me though. I'm a fan of detail, and detail is something this really doesn't have. I think you took it on a good background though, and focus and clarity look to be good. Just doesn't really appeal to me much.
