Hello and just what city is this? I have no clue as I'm not familier with most city skylines, LOL! :)
This has the potential to be a wonderful great shot. The idea is there, the composition is there but the post processing really hurt this one in the end. The halos around the building, the tilt on the horizon and the uneven colors really hurt this shot. Also, while you used the 640 on one side the other side is so short you lose the chance to really make this shot work.
The bridge coming out on the right hand side is not needed IMHO, if you cropped it tighter on that side and then straightened it out and don't sharpen so much it leaves a halo, add a noise filter if you need to. If you rework this I would love to see it!
Not bad, and with a few adjustments I think this could be better. It seems to be tilting to the left and I wonder if rotating the horizon a bit clockwise would help? Also, and this is just me personally, I find that black and white or sepia photos with grain have greater impact than color photos.
This is a nice photo. And it leaves me wondering whether or not the grain really enhanced the image. To me, grain works best in photos that are dark, contrasty or moody, or to provide an "aged" look. This seems to me like a good image that had grain added to it for a contest, rather than an image that was enhanced by the use of grain. Keep shooting! :)
