daily painting practice - still life study coffee break

painting on the pre-toned board allows me to jump right into darks and lights. The mid-tone is already there.
This is a very mono-tone painting. The key I think is leaving plenty of warm transparent shadows.

Coffee Break
8"x10"
oil on masonite

Every time I go to the thrift store they have hundreds of coffee cups. I finally broke down and paid $1.28 for these three. I have wanted to do a coffee cup still life for a long time. Of course being a tea drinker I know I am committing blasphemy with the title.
