What Not to Do in First Painting

-- use small brushes and blend...
This week I worked on the eye, the forehead and the crown. I was criticized for doing too much blending on the forehead as if I were finishing it. This is something that has to be done anyway in the second painting stage so it's considered a waste of time during first painting. Juan also said my paint layers appear too thin (another danger of blending)... and so he recommended this preferred method:
1. Paint with a larger brush (1/4 inch?) and use differents of it, not just the flat side.
2. Use quick strokes and lay down square panes or blocks of colour without blending into previous squares (although this will be inevitable when painting wet on wet).
If done correctly, the painting looks blended and finished from a distance but choppy when viewed up close...
3. Then in second painting, work up close, blending with smaller brushes for detailed work.
