The different elements of this photo work well together. I especially like how you've incorporated the rainbow. It seems tilted slightly to the right. The Levels are fine as they are, but darkening the midtones a little might make it more dramatic.
Good question! As for the shot itself, overall a nice shot, could have cropped up a bit more to lose some of the black on the bottom and I would have scored a bit higher
The capture of the rainbow is good, and I like the drama in the sky, but the image seems tilted or else the perspective is off and that seems to reduce the overall impact.
For my liking the building is too centre of the shot and it dosn't appear to be very level, great selection of colours in teh picture though and pleasing to the eye. Certainly a Urban Landscape in my eyes and you have met the task in providing the shot required. Shame the sky wasnt a little bit punchier though ! Good work :0)
