I painted this last night during an impromptu broadcast (and recording) and tried out this sample panel of ABS. It's a plastic with an ivory-like surface. Very smooth, but not slick. I liked it a lot.
Most of this painting is faithful to the reference photo, but I changed the brown and tan patterned pillows to red, took the soda can off the table and replaced it with a wine glass (which I'm blaming on Diana Marshall who suggested it).
I really like this painting. I might fiddle with it more later, but this is how it looks right now.
The recording is here.
