Hey Gazu! I might in the future. As useful as tutorials are, i personally learned most by picking apart others work, as well as the sbs files that came with SD. If it were a paid job, I could write a book on how to make neat materials though, but I'm afraid that paying bills is higher on the list then make free tutorials…
Absolutely love you substance work. have you thought about doing some tutorials on how to create such amazing closeup resolutions, effects and height maps?
