Tojo, appreciate the commentary. I agree completely that the hull is not weathered enough. The challenge is that I had attempted to depict a soviet gun after a snowfall. I had airbrushed a coating of dirt on, but it did not look good. I think some drybrushing above and below the snowline is in order. I've also recently picked up some pastels, so i'll see what I can work out there.
I appreciete the feedback!
