Found these thumbnail sketches for scene 3 while reorganizing . Thinking through a scene with tiny drawings is a good way to save paper. I also found a few unrelated thumbnails that are posted on Sketch-A-Doodle Doo.
Below is the corresponding pencil test. A few minor adjustments, and it needs some softer settles, but for the most part the scene was figured out and just needed inbetweens.
