Thank you very much, I will be working on more materials, soon you will see them here :)

Also i've got to say this: it's the most complicated and most impressive node tree that i've ever seen in bender :) It would be great if you'd make some leather materials of that quality.

Of course I have looked at the leather materials and much more, in fact I am already analyzing real references and looking for how to create them in blender always method procedural :D :)

I've made my own procedural leather in my latest blend, but it looks a little bit like plastic of some kind :/ But i'm still learning about materials and i don't have proper hardware to comfortably experiment. Anyway, it's great that you're doing stuff like that, as far as i'm concerned effects of your work will be truly amazing. As for the procedurals themselves i have to mention about blendswap users CgAlpha and Elbrujodelatribu, they are also authors of some very good and accurate materials.

Sii there I made that mistake since I did not know the rules very well but in the next I will fix those details :D
