I think it needs more details
What do you think?
I think it looks great! I like the detail you gave to the columns at the base. The only suggestion I would make is maybe making the white just slightly darker.
Honestly, I think it’s great as it is! Once you adjust the lighting and add more skyscrapers, roads, etc it will look much better!
maybe you could double the amount of windows it has, i don’t know what the inside looks like (if there is one) but the windows look pretty big
other than that i think it looks good, and it’ll look even better once it’s combined with the rest of what you’re building!
