I hid my background layer, then made a new layer on top of the layers containing Shinji's details to rough-sketch the basic shapes that comprise his head, neck, and shoulders. I included the guidelines that I generally use when sketching basic shapes, as those guidelines are good reference points when drawing successive frames.
Just a little quirk here, I prefer to do these sort of rough animations in a light, bright blue--force of habit from working with pencil-and-paper animations, as it's almost tradition to work with non-photo-blue pencils before retracing in 2B pencil, because the shade of blue of the pencils is just the right color that it doesn't show up on copies.
