huge fan of how you have atlased your textures =) but somehow the red brick texture + the lighting doesnt work well in the shots it also turn down the "chromatic abbreviation" or what ever its called where the color channels get shifted towards the edge of the screen
very nice over all. however i have few comments.. when you said military warehouse i expected more of "military" hangars, tents and wired fences etc. A brick warehouse? i dunno. your normal map, baked out of an image isnt always a good idea especially with doors and windows.
Overall i think it looks awesome, however the repeating metal shutter texture is the most obvious due to the fact it has the identical graffiti marking on it. If i were you i would remove the graffiti from your main map and great a separate graffiti atlas to place as decals around the environment. You can then place them…
