Ciao Ripster,
I like it a lot! The figures are going to come out great, I bet. One thing I noticed is that the overall appearance of the Ket is too white. I don't know if it's the flash or just my old eyes. Unless this thing is one completely frozen snow, there would probably be some mud or dirt marks on the running gear and front wheel. Plus, you might want to think about a wash on the topside just to pick out the small details.
Just suggestions, of course. Keep us posted on this small gem.
Ciao for now
Rob
