NICE! To push the size point even a bit further, you can add a copy of those birds, but much smaller, next to and overlapping the Colosseum. This way we get a sense of space (some birds bigger and closer up, and some smaller, further back away from us but closer to the building), and the smaller set of birds will really sell the building size because we all have a general idea of how big birds in civilized, populated areas are.
