I can see the base of the glass, and to me it does appear to be resting on the surface, but I do have to admit it's maybe just slightly not. Maybe an optical illusion. I would suggest maybe not using blurred transparency. I like the surface, but I think a nice wood grain with a slight blurred reflestion might be cool, but I think I'd make it a glass tabletop with blurred reflections. But otherwise, it's got a dreamlike appearance to it, and if this were to be for a CD cover, I see no reason to drop that idea. As for photorealism, I think you got it pretty good, but again, the glass is sort of unusual, being so blurry.
