I really like the general layout it definitly feels like a city. However I think the buildings seem to clean for a ruin and over the top mossy.(for example its not stained by rain, theres no damage[no smashed glass, missing bricks etc]) and i’m not quite sure on the lighting.(the fire looks lovely), but the general lighting seems quite normal(which is fine if that is what you really want), but maybe a darker tone would be nice, with some thicker fog?
Anyway thats all the faults I can see and the level looks good overall :D.
Some advice: A quick grunge map overlay would make the buildings look alot more ruined with minimal efforts.
