Seems to be lacking color, or some extra detail. It looks good, and I really like it. But it seems pretty bland in my opinion.
Maybe a few small scratches or blocks around the image to add to the radius of the piece. Everything is just at the center right now. Instead of giving us a choice of where our focal point would be or having us find it, you're making it obvious and having something only in the dead center.
Still though, great job. Just add a bit more. 7/10
