Those guys came out GREAT. The uniforms are very nicely weathered. I used the kneeler in my Cold Stare and I think you did a great job with him.
The scene is very good, subtle, simple, very nice scene. I like the photography too.
As this looks basically done my comments are things to think about for the next go round. I would also say, if I were you I wouldn't change anything on this diorama - its good as is. The two things are- foot prints in the snow?? I struggled with testing this on Cold Stare and opted to create the scene around it. Convincing foot prints in shalow snow are not easy. Secondly, more rubble may be in order. I say may be because the scene is small and focused and the sparse rubble does not detract from the feeling I get. So this is personal preference and you did fine on this one.
Nicely done.
