Well, I couldn't answer until I'd had an artistic lead in from Mark and Neil . . . .
Actually, I think that you both have good points.
Still, first of all I should welcome Jim - great to have you hear, please do hang around.
Marc. whilst I understand you . . . I think your Chihuahua is a pretty poor substitute for Irakly's alligator . . . (one of my formative photographic moments was having Irakly point out that picture I was proud of needed an alligator in the top left hand corner).
I also agree with Seascape about cropping the cars. . . .
Surely the point of the picture is the visual impact . . and it does have impact (surely we can all agree). It isn't boring, and it isn't unattractive, and it has a bit of the down and out to give it a feeling of weight. There's plenty of human impact . . perhaps adding an actual human (or a Chihuahua) would simply transfer the impact and change it into something quite other. (my picture really DID need an alligator).
Neil - post processing surely is wonderful . . . as long as it isn't just an end in itself (and I don't think it is here). As for being a red rag to a bull, Jim's an intelligent guy, he thought he'd like to join in here, and surely this is a good way to do it?
I actually like the picture (apart from agreeing with Seascape about the cropping). I'm not sure that it has a great deal to say . . beyond the aesthetic. . but perhaps that's a good thing?
