Basically what I'm saying is, the diffuse textures are bland, and I wouldn't know how to go about making them look as they do in game; However, Turbo and RatchetMario have the Photoshop skills and know-how to do that. On top of that, Turbo knows how to turn the 06 world space normal maps into tangent normal maps. I read his tutorial for them, but I don't have enough confidence to try it out. (I would just submit the normal maps as-is, but the lord above knows that tangent normal maps are much more useful...)
Here are some examples, though: (Sonic's diffuse and his normal map, respectively)
