At the very roughest beginnings of a sketch page like this, a lot of what's considered is what takes up space where, how things out in relation to each other. Things are drawn so quickly and intuitively that in spaces like panel 3, it's hard to understand anything other than the shape of a person and the sense of motion. However, in the last panel, you can clearly see a drawing that, even in rough form, says the panel is going to stress a character's ability to emote.
