Except for a height issue, there's really nothing wrong with the body under all those clothes. As he is, he looks properly proportioned. I won't change the body as I won't have him standing with anybody anyway.
Overall I have no complaints about this figure. Boots and gloves may be a little dark, but it's not bothersome to me. Love the jacket and suit. The helmet could be more accurately weathered, and I may do that eventually, but there's nothing distractingly off about it. The head sculpt looks great with the helmet on. I'm satisfied with it, especially with the Ex glove holding hand, which keeps it from being strictly Hoth. I passed on Red Five, so this is my definite X-Wing Luke.
