I voted this a 6 because it's technically pretty well done and it has a pretty arrangement. But ultimately, it doesn't hold my interest for that long. If you like it, though, then great! :)
I really like the simplicity of this one. Nice bright colors without being oversaturated (many others in this challange are WAY over saturated) and the glass serface is a nice touch. If the DOF was deep enough to get all of them in focus it would be even better IMHO.
