There are some works that are hard to point out mistakes, your image is one of those. Looks like frame from game set in the future. I like the foggy mood and structures showing that the city will break away from the ground even more. Hope other images will be good as this one.

thanks a lot Jakub, for such words, you made the day,
as for other compositions i hope also to see it well am having hard times right now to but all together.

regards
