Okay guys, I'm not sure if this counts for anything, but a friend of mine pointed out a consistency with the Rayman mugshot in the character select screen.
The lines being all jagged could just appear to be a sign of sloppy editing, but notice how Sonic and Mii also have them. And if you look at an official screen, the lines still look jagged. So what we actually have here is a constancy with Rayman and every other character, which wouldn't seem to be the kind of thing someone faking a screenshot would consciously notice or do. If all of this counts for nothing, I'll go back to posting pictures of lums.
