My favorite sculpt has to be T1 T-800. Barnes is next.
I don't consider myself any kind of expert on Tom Berenger but that Barnes sculpt looks like him through and through. I think that one could be the best likeness I've ever seen. Its why, though I cancelled him, I quickly cancelled my cancellation!
