The first photo is the charcoal sketch using a grid to draw it on the canvas. The second photo is the Imprimatura Layer which basically established a mid-tone layer. For this layer, Burnt Umber and Burnt Sienna was used. The third photo is the Umber Layer, establishing the darks and reestablishing the elements in the painting. As you can see, I have only worked on the roofs. The canvas is 12" x 12" gallery wrapped.
