How to paint a dog shit - step 6

"Sfumato is one of the four canonical painting modes of the Renaissance (the other three being Cangiante, Chiaroscuro, and Unione). It corresponds to the concept of 'low-contrast' in photography. The Italian word sfumato (pp. of sfumare, 'to vanish' or 'to shade') captures the idea precisely. The finished product appears as though a veil of smoke had drifted between the subject of the painting and the viewer"

Use a dry brush and some remaining shit colour to add some sfumato to your painting.
