I finished two pen and ink drawings this last week despite being distracted by a missing cat. My very old cat got out when I wasn't paying attention properly. Perhaps I did the drawing so efficiently as a distraction to keep from worrying about the cat. He got home on Friday night but he had to be rescued from a high wall in the dark.
The first drawing I finished was this tiger. It is pen and ink on graphic film with coloured pencil on the reverse. It is more challenging than you would think to get the right tones to show through on the right side. Graphic film is translucent but not clearly transparent. So colours are dulled, and blending one colour over another needs to be done backwards. You have to use brains more than feelings.
