I usually read defaults or smudge tuts. I know the basics about brushing and there's no much else to learn from there.
Usually Smudge and Defaults (aren't defaults and no brushing the same thing?). I like reading them all though if they're good, only ones I don't like are C4D. :lol:
Fractals are my favorits sigs, and defaults only but there arent many fractal sig tuts so whatever defaults only ;(
