The composition is very nice, I like it a lot. Symmetrical with one major symmetry-breaking element. This is textbook "why centering works sometimes"
Not in love with the tonal qualities, this looks very artificial to me. HOWEVER you've done a great job of conveying mood and idea here. When I see processing this heavy, I have to wonder "was he going for a cool look, or did he have a visual idea?" but since this one IS more than a cool look, I am imagining that you were going for more than a cool look.
This is not the kind of thing I like, but I think it's good.
The fenders seem to blend in with the rest of the monochrome composition though. I know the mood you are trying to set, but I would like to see it in its distinctive colors, as if I was standing right there. Good shot.
I am with amolitor on this one. HDR and especially b&w HDRs at some point start to look like regular graphics and this version of your photograph is going strongly in that direction. Now this: Sensazioni by ~DiegoKoi on deviantART
looks more like a photograph than your creation, yet it's not a photograph at all.
Nevertheless I like the dynamics of your photograph.
