Once again, I am absolutely pleased with what you have made until now. The scene looks very nice and the work involved is really notable.
Okay, following Roman suggestion I have a couple more for you.
1> Please tone down that streaking hair color of the civilian (it may be the pic though). For that you can completely re-paint the hair in another shade or (what I would do if I were you) just apply some small dotting in a darker shade overall. You will see the impression will change greatly with very little effort by your side.
2> Maybe you have something in mind as the scene is not compelte, but apart the civilian one or two german tankers would complete the story to me. In my opinion there are (for example) some very suitable Tamiya figures for the scene you can add quickly. Email me for more details and we can follow the conversation off board if you want.
Suggestions apart, very excellent work amigo.
