Sean Cheetham is an excellent Artist, I've learnt a lot from him. I've never used oil paint before, but I truly enjoyed his class. Here is what I've done during his 5 days "Alla Prima" Oil Painting workshop at LAFAA... or more precisely, the 2 last paintings. Each one of them is approximatively 6 hours or work.
This is Day 5: (using a limited palette, know as the Zorn palette, Anders Zorn) White, Ivory Black, Yellow Ochre and either Vermilion or Cadmium Red Light or Med, in that case I used Scarlet Red.
And below, Day 4.
