Working on my largest canvas to date...

Yesterday, I decided to tackle a 36 X 48 canvas...my largest to date (my second largest is 30 X 40). Working quickly, I established the great lines of the composition and the orange under painting. However, I felt the need for a pregnant pause before proceeding with the 2nd coat. I think I will proceed with a palette of oranges, purple reds and purple blues, California style...We'll see.
