Flurry of sketches

I spent the afternoon painting with my youngest. She was so excited when I let her use "mommy's paints and paper." So, while she was painting away, I decided to paint these small pieces.

Blue-footed bobbies are one of her favorite birds. This one is rocking out to Lady Gaga.

Today is allowance day in our house. I'm guessing this guy is checking out how much he's saved up.

Is there a word for the painting equivalent of doodling?
