I've been having fun with the contemporary collage style mixed media / multi-media ATCs in a way where the variety of media is intentionally obvious. I decided to switch up methods and use mixed media for a traditional art style. The wolf is in colored pencil and the rest of the ATC is watercolor. I'm really happy with how the fur, sky and trees came out. The white watercolor snowflakes are really pale, maybe I should use watered down acrylic paint or guoache next time for snow.
An artist whose career has hinged on a two media style is children's book creator Jannell Cannon. She uses thinned washes of acrylic paint for the background and Berol Primacolor pencils for the characters and foreground.
