We haven't gotten around to getting some good pictures of the models, so this is all I can do for now with my phone.
The two walkers make everything look even cooler, and I personally can't wait to get started on the next 10 vanguards!
So for me the painting schedule looks something like
2-4 Kastellan Robots
5 More rangers
1 More walker of some kind
... And a knight at some point :D
