Wow, atmosphere and light is magical! Color scheme is great, the view and composition also! Your work is definitely one of the best, just few things I can point you to get even better quality - first - maping on the structure - balkonies has visible tiling. Perhaps it would look better with plain color, no texture, or larger map. Other thing is grass in the bottom. I would sugest little more sand, less grass...
Anyway, keep up, you are striving for the top! Good luck!
