Focus on local values when designing a character before putting it under different lighting scenarios.
The local values can make the character easily recognizable but also bring the eye to the desired point of focus by having higher contrasts between black and white at that/these spot(s).
Big-Medium-Small
In terms of shape
In terms of concentration of details (typically we’ll tend to clump small shapes together around small spots to give a clear idea for the viewer to what they should look at, especially next to big areas that dont contain much detail) - use Arucelli’s twitch saved part of VOD & the video of the chinese guy drawing the dragon girl
Big-medium-small can also apply to smaller shapes inside of shapes.
