Thanks for the comments.
My original idea for Cadians was to do them as highlanders. So I put together a few test figures a couple of years ago. This is one that is finished (other than the base). I like it, he’s a real mongrel mix of models - legs and torso from Kromlech, arms from Anvil, head and helmet from GW, back pack probably Kromlech.
This has spurred me to finish a few more, so that’s another bloody project to add to the list!!
