The distance in objects between their locations from one page to another determines the frame resolution that defines the quality of the animation.
The intelligence level of the flipbook is determined by whether each line follows a course of action that is consistent in its design by the direction and flow of its movement.
Resolution that are followed in the flips to come will be quite detailed in their design. You will see a sharp contrast between the difference in their styles as your skills progress. It may take time, but that's what you learn when drawing high-res flipbooks: life is really, really long.
