looks good...

can consider... do a depth-of-field look, blur the further "towers" & background

Nice image.Try blending the edges more they seem hard .

very nice,but i would blur the edges a little just to blend them in a little

The stacks need a darker shadow, they look like they're floating. Also the woman closest looks like she is jumping off the stack not sitting. Perhaps adjusting her dress would make it look more realistic. Good luck!

I really like this style a lot! The mystery and thought provoking mood of this is very pleasing. Wonder how they all got on top of those stacks. Doesn't matter....it's cool. Nice job!

beautiful
