I'd give him a B- grade. He's got all the problems the AT-TE gunner has, including those wonky elbow joints and wobbly ankle, hip and knee joints. He comes with a stand which is good, because he damn well needs it.
Having said that, he's pretty good looking. His paint is more detailed than with the Jedi Temple Assault set clone, though mostly because of the two thin strips going down the side of his legs.
His shoes up to his ankle are dusted up which actually looks okay. But for some reason it makes his feet look smaller and as the AT-TE mold kind of already has the look of a big-headed, big hipped clone, this isn't exactly appealing.
His helmet does come off which is a plus, and it fits pretty well. His elbow joints are a pain in the arse to maneuver and the left elbow frankly pops out quite a bit on the first one I opened.
There's something vaguely dynamic looking about this clone (he looks a bit sleeker than the AT-TE gunner), and the "damage" looks pretty good actually, but he's no more than a solidly above average clone. He's got the same face as the AT-TE gunner underneath.
