I have finally finished the portrait of the two cats. Whew! It was a long process, but I am very pleased with the result. The final image is about 8.5" high X 15" wide, so I had to scan each cat in separately and combine them in Photoshop to get them all in one image here.
I added some shading in blue underneath each cat to give them some grounding within the drawing. I chose blue because it contrasts nicely with the orange color of the cats, and in one of the photos I worked from, the cat was sitting on a blue blanket.
