These are the thumbnails I did for the planning of the scene. They were done fairly fast and with most thought put into the man. The waitress will be posed a little diferently in the actual scene. When I planned for this scene I tried to make room for change in the characters poses. I thought about directional change as well as up and down especially.
I use thumbnailing to get an overview of the scene and to start getting into the timing of the scene, only in broad strokes yet though.
