DB, you've gotta admit that the Chewbacca would look kinda cool in a pirate gang or something. It's so freakishly off from the final thing, that it just stands out as a unique alien to me.
The Vader, I agree there's a little disappointment in me in how he turned out, and he's definitely not easy to manipulate into a diorama/scene. He doesn't "fit" with the other line figures. What he does well is just sorta stands there as an homage to the art if you're into it... I am so he's good for that, but I mean he won't slip into a background of some diorama, that's for sure.
Chewbacca's already getting ready to invade my shelves though. He just is too funny looking... I think he'll chill in my Cantina.
