Yeah I've noticed there really aren't many good tutorials on modeling/texturing around these days.
While the likes of BJ and Spex do custom models, I myself mostly use a method known as mesh modding, which is using different parts of models to make one better or completely different model.
A good example of this would be the Cloud model I'm updating

And to unify the different parts I just put them under one big, nice looking texture.
I guess I should have outlined a character model I'm working on that doesn't have a 3D model, but I think using a finished product to show off how one can make 3D models from mesh mods is better over all.
I could make a diagram of my current model once I'm done I suppose.
