I'm trying to think of what else this picture needs. It just feels as if there's not much depth to this thing. I need to find another media to spray paint on in the garage so I can make another "drip" to the yellow "spoke" and possibly make that bigger, but other than that, I'm out of ideas.
In other words: Criticism wanted
Note the subtleties, I had to bring them down because in print, I'd have to really make it opaque for it to be even subtle with my Canon i9900.
