Snow Birch is a test of your liner brush work! I always passed this painting up because I thought it would be difficult. I didn't realize a lot of it was acrylic work. I'm pleased with the results overall. Another member was commenting on the use of high quality gesso when doing this painting. I agree. I didn't have white gesso. I used Liquitex acrylic, but had to go over all of the foreground trees twice to make them look correct. This is a fun painting! Over the acrylics I used Ross oils on a 16 X 20 canvas.
