Tag the composition on this painting you guys

Jerome Witkin. The act of Judith. 1979–80.
My freshman painting teacher introduced this painting to me and used it to teach color theory. I emailed him to ask what it was called because I couldn’t remember. He replied with the info I wanted and included a copy of the painting. It’s higher resolution than I could find online, so I thought I’d post it. It’s a really nice painting.
