On the official Monkey Island Facebook page, LEC has followed up their gradual releases of MI2: Special Edition screenshots (by the way, I don't think we mentioned the last two on the front page) with some gradually released character concepts. You can see Herman Toothrot's transformation from 1991 sprite to 2010 sketch, but you'll no doubt be most interested in the various passes they made at Guybrush's revamp (v1, v2, v3, v4) before landing on the final version, especially with regard to his age and similarities to his CMI counterpart.
Update by ATMachine: V5 Guybrush can now be found at Kotaku. For those who've been having trouble viewing the previous Guybrush concepts, the link also contains color-corrected versions of those, which should alleviate the problem. Be sure to right-click on and "View" the images to see them full size!

Then again, I'll probably get used to him after playing the game for a while.
It just annoys me a little that they always seem to end up with one of the worst ones.
They should have showed us this when they were still working on it, to at least get a pointer to what the fans wanted.
V3 looks the best to me. I love the fact it heavily resembles the CMI/TMI Guybrush.
Snugglecakes, these are only concept art aren't they? I don't think it's worth worrying about too much — the in-game hair looks great from what I've seen.
But I love Herman v1. :D
