Owl and Squirrel Background

Here's an establishing shot from my Senior Project animation about an owl and a squirrel. If you look closely, you can see the owl perched atop the hero tree in the shot. The camera will be slowly zooming in on him in the animation. I painted the piece in greyscale first, then colorized it, all in Photoshop. I actually like the grey version a lot too, so I'll post that as well. The trees are from a custom brush I made.
