Watercolor on arches paper is so lovely, I've decided, especially when I get to layer the paint over one of my pencil sketches.
I also love gouache. This observational study above probably took about 2-3 hours. It's not my most favorite work in terms of anatomy/accuracy and all that jazz, but I did enjoy the colors and gouache is growing to be one of my favorite mediums this semester. It's so flexible to work with on arches paper!
