Here is a force that I painted up for a client just a little while ago. The pictures are really just representative- I didn't actually get a photograph of every last jetbike, but I did get one of everything once.
Aside from the War Walkers, what are on the bases of the other models? I recognize what looks like static grass, but what's the crumbly stuff made of? It looks a heck of a lot more realistic than the flock I use [because it is cheap and easy!].
