The minis are from 4A miniatures - an excellent new company that is well worth checking out if you haven't already - http://www.fouraminiatures.com/page4.htm
Service is great and I love the weird little minis they make. Oh and Andy, whose venture it is, is a thoroughly nice bloke too - was glad to have a good chat at the Vapnartak show in York a while back.
Anyways heres the minis - I spent as bit more time than normal on these chaps not only because they were for a comp but they're really nice to paint up too.
I have the other 5 goblins 4A released in the paint queue and have a game in mind for them - just need to build a large swamp first...!
