I think the sky is too powerful Pete, at least in a small image like that, it grabs my attention all the time and the buildings are too small to fight back.
If I'd had more time I would have gone closer.
oooh! I just had a play, cropped it as suggested, enlarged it 200% and it looks just like a painting, cool!
Oooh! Is nowhere now safe from Pete, his 10-20mm, photoshop skills and, no doubt, his hamster!
Okay, hyper critical, you deserve it.
Any way you can get rid of the crane, it sticks out like a sore thumb and spoils the image.
Like Steep I think the buildings are a bit weak, they look washed out compared with the sky.
Really novel take on it though, I could see that selling pretty well actually.
Great shot Pete ... HDR'd or not as the composition is quite stunning ... spoilt only by the buildings in left half leaning in ... and emphsised by the crane Dod wants rid of ... imo of course ...
I think you could probably lose the big black patch top right corner ... and improve the composition as well as losing the dark area distraction ...
