Nice dramatic sky above a decent night cityscape. The blues f the sky play off the yellows of the city lights wel.
Some voters may fault you fro making image colors look unrealistic. They will not think that is the way it really was and voye you lower because of it.
General technical quality is fine and detail good. Highlighting the sky in the crop is correct but you might want to include just a little more town and a little less sky since the sky is least interesting at the top of the frame. It would also fit the rule of thirds which is never a bad thing.
Sorry for the form-letter type commentary. I’m going to try to give almost everyone at least this breakdown to start. I would be happy to offer a more detailed opinion if you would like, though I don’t consider myself a very knowledgeable photographer.
Here is how I broke down my score for your submission.
Content: 2/4 (Is the subject compelling? Does the choice of content match the challenge?)
Composition: 2/2 (Is the work well balanced and successful?)
Color/Light: 1/2 (Is light and or color used with skill and artistic intent?)
Clarity: 1/2 (Is the picture in focus? Are the elements clear?)
Total:6/10
There is noise in the picture that you might want to consider removing, and it looks almost as if you took this behind a window (slight reflection in the purple). Perhaps the saturation is a bit... hard.
Although I doubt that they are real, I love the colours in the sky. There appears to be some noise/banding in the top left - but this may simply be a camera issue at high iso settings. Good composition with the horizon at just the right leve for this image.
