This map actually put a smile on my face. I really love the visual style, and the layout might be the best one here. My only problems with the map are small nit-picks.
This prop looks very out-of-place, and I'd suggest replacing it entirely. Putting a ramp here may also be interesting.
Changing the bricks on this prop to gray and adjusting the color a bit would look a lot more fitting.
A custom graffiti here would be very fitting.
These rooms would look better with some new wall textures and details. Some custom paintings or furniture could also go a long way.
Anyway, this is surely one of the greatest entries. You won't even need me to wish you luck, because you've already secured the top three with this map.
