“Clustering” is the second in a series of drawings in the year of covid-19. The central figures, including the snag, is a 100% natural image taken from the heartwood of a myrtlewood tree. The first drawing can be seen in the March 2020 post.

Central figure of vultures clustering on a forest snag is natural pigmentation of the myrtlewood tree, revealed in a cross cut of wood, and super imposed into a pencil drawing.
Amazing work Terry. You are so talented and smart. I am very proud to know you.
