Blood for the Baron!

I'd say try doing the camo only first as you could always do the whole thing if you're not satisfied with the result. The canon is a bit bulky perhaps. Weird, I'm sure I saw one of these in a charity shop when I was down south at the weekend - it was something similar, but didn't have time to take a look at it. Looks like Lanard?

Personally I like it as is.

If I were to paint it, I'd go Space Force.

Rather than a sticker, why not a hawks head to match the helmet!
