One of the offshoots of getting back into D&D is a renewed interest in gladiatorial minis games. I still haven't found the right one for me, though Blue Sky, Red Sands is close, and the Mordheim Pitfighting game is familiar.
These are a little more roughly painted having been done a few years ago. They are mostly Games Workshop Mordheim Pit Fighters, one of which is converted by adding a Foundry gladiator head. The fellow with the red tattoos is a Celtos fig ... I think; I got it free from someone. The shield it holds also is from Foundry.
