The gentlemen on the left I used an Empire Militia head, gives a nice classic piratey look. I'll Call him Patchy.
The guy in the middle is a Bob Olley sculpt and has some unusual proportions. The head I used is probably a bit too large and initially looked terrible, but with the addition of a shoulder pad it helped tie in the scale. He has tiny little feet though... He looks like such the hard bitten warrior of numberless campaigns... then you see his dainty little feet! I'll call him Därthmäl Twinkletoes
The last guy is one of the infamous space Celts you've heard so mush about. Used heads and hand from the Warlords games Celts with some green stuff to tie it all in. He's called Brenus the Brainless or maybe just Biff.
