Do you know why Mario's face is so different in the reflection in one of the Mario Kart Double Dash renders? My guess is it that it's from a rendering technique that requires a 2D image. Metals require something to reflect off of to look good in a rendering environment. This requires use of an environment map, a 2D image placed around the model (to save time making a complete scene). I think what happened is that they were using an environment map meant for another render and maybe they decided to change the facial expression at the last second. But this is my best guess, but it makes more sense to me than anything else.
BTW if you look at this render closely, particularly in the shell's reflection, it doesn't seem like Mario and Luigi are even on the kart. I'm pretty sure it's another environment map thing.
