I tried to work in dawn/night settings, but only this worked so I guess there you have it.
Would add more trees to the background, some smoke and so on.
It looks kind of cartoonish, the AO makes your pic look cell-shaded for some reason.
Yeah idk. On my main screen it looks great, but on my laptop and cell it looks really weird and unrealistic.
Definitely needs some more atmospherics, smoke, dust, fog, etc. Warfare generates huge clouds of shit, especially the WWI 24/7 artillery bombardment kind.
