This is fucking awesome! I really like the red version of Daves character. XD
Would either creators care to explain how they were made? I'm curious.
I'm not one of the creators, but they look a lot like Warhammer miniatures that have some clever customization. Those often come in pieces (like arms, set of legs, torso, head, weapons) and then you sort of cement everything together based on the equipment you want the units to use while playing and paint them.
