I recently started to teach Pet Portraits in Colored Pencil to the brave souls that also took my Pet Portraits in Graphite class.  This is my sample.  The photo reference is from a series taken while working on a commission.  The Border Collie Marley was particularly photogenic.  This piece is 9x11"various light fast colored pencil with solvents on Rag Mat Board.  I used many of my tricks on this.
