So I see a little visual pun in there, and a not completely unpleasing arrangement of shapes? Too much reflection relative to visibility-through to my taste, and while I like the reflected barrel, I don't much like the actual barrel.
More to the point, though, there's no there, there, in this one. It's a visual pun and that's about it. No story, no ambiguity, and not even anything particularly attractive to look at.
It doesn't work for me.
