I'm currently making a process guide related to this although it isn't done yet. I haven't started with  the overpaint one. 

I'll be posting the process guide on this one together with the overpaint although I think if you open one of the psd files, you'll kind of get the gist from just opening the folders and sifting through the layers how some of them were done.
