I didn’t see anything wrong with the second bandolier. I’d happily take that and a fur recolor, be it gray or reddish or whatever works. To me what makes him look like Chewie is the “costume” (of the character), and not his face. So if his name isn’t mentioned, he doesn’t particularly resemble Chewie in any other movie, and he’s dressed differently, I think it’s a safe bet to the audience not to infer that its him. And if you go on to see the other movies, there’s no reason for it to be him anyway.
I do thank you for trying a hand in this and I like it.

This is one change that I don’t mind a less than perfect implementation for. Have you SEEN some of the special effects in this movie? 😛
