Skeletal structure of a movement-

In simplest outward term, the controlling elements in an animated movement are extremes and inbetweens.

Extremes are the skeletal structure, a framework that defines the path of a movement. (A path includes direction of travel, distance and arc for all the joints and compartments within a structure to unfold).

Inbetweens is the time-clock an extreme takes, to travel from one to another; its texture of velocity is linked to the spatial arrangements of the inbetweens (timing chart).

Our workflow to animating is the way we each decide to approach the arrangement of extremes and inbetweens.

The texture of an animated movement is really affected by the way extremes is being arrange within a scene, in orderly forward manner, or jumping back and forth, in relation to the spatial gap between extremes.

This motion texture resulting from a particular workflow is much more noticeable to hand-drawn than in CG, because in CG, one can option to readily preview a movement in real time while striking extremes, adjusting positioning as needed; unfortunately not so easily for hand-drawn (since speed is control by amount of drawings).
