Isn't that a similar technique to Dave King's old tutorial where you have a layer for base colour and a layer on top (set to hard light and filled with grey) for 'shading', adding light and dark tones (or painting with a mid grey brush set to bevel-emboss)? Can you give us an example? I tried to find Mr.King's tutorial…
Ok, Jehuty. i will try and write some kind of tutorial at some point. I am a bit busy at the moment wiht work, but sooon as i am free I will do a step by step .
@ Ruz: this sounds pretty interesting but i have problems following your expanation... so the quastion i have is can you make somekind of step-by-step (mini)tutorial for it. if you have time of course.
