No, I've watched many tutorials, but I've taken a mosaic approach now -- cutting and assembling a rough draft before painting the final textures. It's a pain in the butt, but it's the easiest way I could think of. I really want to finish this model already...

I imagine working with ZBrush is somewhat easier.

Or substance Painter which is what I use :

it takes some technical knowdledge to adapt the output PBR maps to JKA's old shader system

I used Pig Brain's tutorial when I did my head, but I guess the basic principles could apply to the rest of the body.
