#1. The underpainting is usually done in acrylic and is basically just a map to show where the darks and lights will go. This could change as the painting progresses.
#2. The first layer of oil paint. This layers brings in the color palette that will be used. The paint is very thin at this point, mostly with paint thinner and a bit of liquin. This will help the painting dry quickly so that I can continue on the next day usually.
#3. The finished painting. I usually let it sit for a few days to dry and then will go back in and do a few details and some touch-ups. I really have to be careful not to overwork the painting (really easy to do) or it will loose the freshness that I am going for.
