I've stayed in acrylic on this number to keep the drying time fast, but still laying it down fast enough in each attack to stay "wet into wet". I'm working in established "old master" stages, b/w, then limited palette, then full color, etc... so far I'm half way there? This one has had three full corner to corner layers of paint, wet over dry, leading to a rich paint surface. Still work in progress but I'm into it!
