After a few months, I finally decided to give this guy an update. I didn't make any drastic changes, but I did make a few additions. I gave him a new set of weapons, made him taller, and bulked his legs.
I'm not a big fan of the black hands; I was trying to go for a gauntlet effect with the lower arms and hands, but now it just looks weird. I wish I had more than one red hand piece.
