I like how you describe what's going on in the drawing. It's not necessary, but it's still a nice touch. I like this probably because it's a more cartoonish image. You don't have to make the picture bigger to understand it. I like how his head is made of wood. I admit that wasn't what I was thinking of when talking about knots.
Eh, I probably still don't get the joke. Squirrels are pretty funny. This was the most humorous drawing I've seen of yours. It really does work. I'm not sure what's up with the negative space at the top of the picture. I guess it makes you eager to scroll down.
