Tyrannosaur Attacking Strutter

This scene from Dinotopia: The World Beneath (1995) shows a tyrannosaur and a couple of allosaurs attacking a Dinotopian walking machine called a strutter. 

In Dinotopia it's dangerous to cross through the jungle in the center of the island, which is ruled by large theropods. The scene takes place as the strutter crosses a shallow stream.

The tyrannosaur is using its powerful foot to pin down the head of the strutter, and is biting off the top of the frill. For a scene like this, I used existing dinosaur models for lighting reference. Trying to guess where those shadows would fall without a maquette would be rather difficult.

The color scheme is limited to yellow ochre, dull red-violets and dull blue-greens. I tried hard to keep bright blue out of the scene.  The painting is done in oil fairly transparently on the dinosaur, with a little more opacity in the background.
