The only reason why Devs are so careful with nazi-related material is because Germany will not sell a game which represents WW2 in a non-historical fashion. Its not an issue with the public; its an issue with sales figures. And sales figues doesn't come into this one single bit, because it's a portfolio piece.
I'm also interested in your texture maps, and your meshes, since this scene does NOT look like it's 3k.
Are you tiling everything you can?
Are you maximising space for things the plaer will see more? IE: Is this gun/newspaper/clipboard using 128x128? because if it is, that's rediculous dude.
