Love it, may I ask what bits were used? At least for the body and mech hands. My only guess is Final Faction for the power claws. he looks like a giant old school Chaos Warrior which is what I like to see.Slave ogryn leader is coming along under the brushes.
I agree the Captain's servo hand is too big for him. I'm glad you said it first so it's less rude for me to comment on it, lol.
I like the idea of two+ versions of the same character, can be fun.
