Hi ...
How about a tutorial that goes from modeling a basic mesh in another software (( modo , maya .. or whatever )) taking it to 3DCoat , do the sculpting , voxels , painting , retopology and then taking all that back to another software for rendering , That would help a lot . If im not mistaken , a lot of ZBrush DVD's talks about things like that and i believe people like them
Good luck .
