I took your workshop and learned a lot.
I have a few questions.
The first one is your use of the transparent block in.
I was taught that you should paint on top of these block-ins as if they were some sort of a map - but you don't - you actually, as you put it "incorporate" the transparent under painting, to some degree, as part of the finish.
I can understand the confusion - I was taught the same thing.
I tell my students who work with me with both Pastel and Oils...
" The nice thing about oils is that they are wet and the problem with the oils is that they are wet."
THE 2 REASONS FOR MY DRY TRANSPARENT UNDERPAINTING.
My relatively dry transparent block-in is scrubbed on so it dries immediately and I can proceed with the painting, thusly avoiding the problems many students encounter after an hour and a half of painting and they are sliding all over wet paint. (This reason is understandable. )
The next reason might not be so clear.
While I was at the Art Students League ( N Y C ) in a conversation over coffee someone said. "A beautiful painting has an inner light,". I never forgot that, and I try to get that as much as I can in my paintings, and in my opinion nothing is more luminous than transparent paint especially when painting with oils.
