Hey Biggles, good job with the figures. I like that you used washes and drybruhsing on them. Many people seem to leave these techniques aside for braille scale figures, for IMO no valid reason. Maybe you could add some little detail like insignias on the caps (tiny white dots) or something?
I don't know if the base was made for the vehicle, but the tracks and wheels really float quite alot.
Anyway excellent job so far!
