Hi all,
I was recently exposed to a demonstration given by Steven two years ago, in San Francisco. I'm in awe with the demo given here. But a couple of things i don't understand here

:
1) Why does he have all those grid lines on his portraits? How does he use them?
2) Why does he have all those blots of colors all over his canvas?
I'd love to hear your views, and i think we can all learn something here. If anyone has been to his workshops before, we'll really appreciate your contributions to this thread here!
