Tropical Rain Forest Toucan - Step Three

Now I paint stronger, more vivid colours into the beak and eye patch of the toucan.  Lighter green is back painted into the background to suggest light filtering through the foliage.  This gives another layer of depth to the scene.

Next, I wash in thin layers of acrylic paint over the mango in the toucan's beak.  I am starting to suggest the grainy surface of the skin and the subtle changes in colour from red to lime green to golden yellow.  The complex pattern of the butterfly is laid in with flat colour before I begin modelling the leafy foliage and flowers in the middle ground.  The tree frog requires careful attention in order to keep it from becoming lost against the green frond on which it sits.
