I always cut out the sides of plastic milk jugs and use them as mixing palettes, and today I decided to use them for concept art and practice. That type of plastic is matte and translucent, so I backed these painted cherries with different colors, to give the cherries different casts. This particular pic is the cherries on top of a green book. I used Gimp to throw some white underneath the shadows. I painted on the textured side of the plastic and went for a smudgy, grainy look. Plastic milk jugs are so useful!
