Slig with hair is really superb idea, I'm supporting this and everything that Lorne want in this remade Oddysee. I want to look at masterpiece - real vision of first Abe game. Imagine the slightly different, darker and weirder Abe's Oddysee. Holy cow... that'll be great in my opinion.
P.S.
Give our Abe

that color and you're my personal heroes...

He looks really (beautifuly) different on this sketch. Is this also Lornes original version of Abe? I hope so.
You guys should really make someday some spin-off game with different art style of every character (something like art above maybe?). Art's of Abe's Oddysee are such masterpiece. They're representing known places but with different design. Game like this could be done. Look at the Zelda franchise. Every game looks different in design. But my idea is to make spin-off (with design changes) not quintology game (god no!). Think about it

Oddworld game which focuses on ART. Not on mechanics, superb story and achievments. Only you (as abe for example) and environment. Only you and feelings. (Look at Journey for PS3 - 95% of players love it with whole soul).
