Here's some Tusken Raiders and Jawa's I've given a base coat to. Once this dries I'll hit it with a dry brush and they'll be done.
My initial thoughts were to do them all with a dirt/grass combo but it just wouldn't look right for the Tattooine creates, let alone the snow creatures. So I've decided to honour their locations so that the Wampa will get a sleet/snow base, Jawas sand, Ewoks forest floor and so on.
Then again anything I come up with just has to look better than a blank black base.
The only concern I have right now is do I rebase the newer minis? I really don't like the square bases at all. I have a metric ton of 25mm GW round bases here but it's going to be a lot of work rebasing them all.
