The lower limbs are shrouded in shadows, just starting to lose focus. Shadows don't just darken areas, they blur edges and blend colors.
I kept to a very simple palette in this little sketch. Too many colors would be muddy and distracting in a small sketch. I used cobalt blue, ultramarine blue, azo yellow, cadmium red, quinacridone red and pthalocyanine green. At the very end I dashed in some white gouache to play up the highlighted limbs.
I'm enjoying my little watercolor Moleskine journal. I usually lean toward larger pieces, but the small bound journal keeps my sketches as sketches rather than fully detailed time consuming paintings. I like that the pages really can't be removed so the sketch must be left in my sketchbook. I tend to get a little bogged down with details when I'm recording a scene. This is so small it reminds me that I have a camera for details, a sketchbook is for what the camera misses, such as the faint orange sunset glow against a bright blue sky.
