I call this one "Blue Life." Media: collaged paper, colored pencil, and ribbon.
Here's "Broccoli Toad." Media: monoprint (the strips of paper in the background), collaged paper, and ribbon.
"Red Corpuscles." Media: paint, collaged paper, stamp. (Do wrinkles count as a medium???)
"Butterfly Shark." Media: paint, collaged paper, embroidery thread.
It seems counterintuitive, but having constraints like these makes creating art more fun and less stressful -- for me, anyhow.
