Treehouse Sketchbook Spread #2

I spent a fair chunk of my holiday playing with my Sketchbook Project book and exploring the treehouse theme. Here's another spread. Click on the image for a larger view.

I chose to go with a more ordinary backyard treehouse because I wanted to get in some practice drawing kids. Then I decided to add a cat. (I thought of drawing a dog, but that didn't seem quite right up in a tree.) Then I added the squirrel to amuse the cat. The bird in the nest (another form of treehouse) at the top was an afterthought.
