WHAAA? :O
IMPOSSIBLE! But thankies, it needed to be said... :P
Oh yes. YES!
Either render the stock yourself roughly if you like, or you layer textures and stuff over the top and erase parts. Obviously it's harder to do as many dense effects, but yeah, it's a different kind of style. I think my next tutorial will be textures. Perhaps, even though I'm trying to move away from them more.
