Thanks, Biggy Bro Slig and Odd Chick, those are the sort of comments that make me want to start on the next one!
It might be a little while before I post a new one because I'm going to be starting on one that isn't Oddworld related and I don't really think it's worth starting a new thread in the NOA&L. When I get back to Oddworld stuff, though, I'll be making a bit more than just a face!
