He's painted very well. I like the smooth white of his pants. I understand the fear of over doing it with dirt and grime. like you said , try a bit next time.

He replied with something like 'I make models of tanks, not the battlefields they fought on'. A different perspective. Keep up trhe good work. We are always learning.
