Here's my Dragon Chally 2. I left off the dozer blade but I might attach it later. The commander is a HaT head with an original body, sculpted by yours truly. This was one of the best kits I've ever built in my life; everything fit just right. Also, it has excellent rubber tracks which are very easy to attach and yet appear to be link tracks.
To paint this behemoth, I just sprayed it od green, then washed all over with black. I also used some of my homemade chalk pigments on the tracks, wheels, mudguards, and ERA.
In the first picture, you might notice some grafitti... er... historical appreciation painted by a crewmember.
