Great idea! make some cloud edges in front of the buildings less opaque, and refine the top edges of the buildings and this will be better. Good luck!

Really nice idea, suitable to this contest! I'd try adding a blue overlay to the city just to take off some of those warm tones in the source. Again, great entry! Good luck!!

Beautifully done!
