Here's a memorial pet portrait I recently created. His name is Amigo, and I was told he loved the beach. It was commissioned by a friend of his owners, as a surprise, so I only had a few facebook photos to go off - not the best situation; I had four photos, he was lying down in all of them, and I could only see his body in one of them. However, he was a nice plain-coloured Labrador, so that made it easier, any old Labrador-body would do. It's when dogs have specific patterns that I don't know about that we run into problems! (PSA: 'Illustrator' is not synonymous with 'Clairvoyant' ^.~)
