Great photo, but I really don't like your title :D Don't take that the wrong way though, I just wish I didn't know what this was (seeing as how this is an abstract challenge)... the title gives it away, when the photo would stand well on its own. I really like the shapes and colours, and the motion from the lens blur really adds to it. 7
The title hurts this, as it removes the sense of abstract for me. I don't want to be told what an abstract is. I want to figure it out for myself.
I also feel that it would have had a better benefit from much lighter background, as the dull grey here darkens the shot and removes a little energy from the color.
