Like what maulfan said the PF is just boring.
Well I don't find it boring, it's really cool, but you have to be a big T2 fan to take something away from it and enjoy that it's a clean Arnold piece.
However, regarding the comments about best representing the character, I don't think this PF is it, I think you have to do something where the depiction is clear you're not looking at a person, he's part machine part person.
Since this PF has the grenade launcher, I'm not sure what they'd do, but it'd be awesome to have a counter PF to this one with full BD, one on each side of a display with other T2 items displayed in between.
