That sounds fun. The downside might be anything about the realistic env that's not 100% realistic VS not stylized about the stylized version would clearly standout more. However, if you nailed the execution it wouldn't be a problem.
Okay, I'm working on an axe for the Game-Artist challenge, and have come to a realization: I'm not exactly certain how to texture realistic gold. Would I simply use the same techniques I'd use on steel, but with a slightly desaturated yellow-orange hue? Or what?
