I don't copy masters paintings to learn, but I do like to try to paint an original in the style of other artists. This is my attempt at a Mike Hernandez style gouache painting complete with opera pink toning of the paper. Although it's done in Casein instead of gouache, they act and look very similar. My other goal was to do it in less than 2 hours because I think this will be my medium of choice for Plein Air painting going forward. 6"x8" Casein on 300lb watercolor paper.
