Nothing really too crazy as the main spire in the middle was excellent and something I could see on Cybertron. As Anarkhya noted to me, you used a photograph for the lower buildings and that is where I had my "human designed" issue. Still a great pic.
This "too human" feeling may be explained by the fact that most of the lower buildings are actually photographic elements. Nice compositing BTW, this is almost not noticeable if you don't go full real size.
