Nice work Arfur9, looks great.
Just a quick tip about texturing for GameGuru, while GameGuru will accept models with multiple textures referenced in the model, it doesn't actually look for the normal, and the specular textures ( _N and _S ) with multiple texture models, instead it used default normal and specular textures, which means it could look worse than low in highest instead of better, so for GameGuru it's usually best to unwrap and bake a texture map and reference it in the FPE.
I wish it would use normal and specular maps for multiple textures because you can actually get a much crisper clearer texture with the textures separate (unless you make the texture maps huge that is).
