BARDLER - The Dude IS the new age Jesus!
And I'll think about his bulk/size-- since he's a caricature he has to be noticeably weaker-looking than Walter, and not look fit. I'm worried that with such a cartoony style, Jeff Bridges' "broad-shouldered" can skirt the line of "muscular" too easily.
Dimfist - I was kinda thinking that too (about the goatee), but I'm worried that finer hair = more detail than a cartoony caricature would need. I'll see if I can't play with it a bit more, thanks!
16bit - He does have sunglasses at a couple points in the movie, but I thought they were too similar to Walter's when I first made these. I might revisit that prop as well once I get the other two characters (re)done.
Thanks for the comments/crits, guys-- keep them coming.
