I want to discuss the specific skill of drawing consistent characters across multiple frames, scenes, or illustrations, because consistency is the professional skill that separates character designers who can work in production from those who can only do standalone pieces.

Consistency comes from constructing the character from understood volumes rather than drawing the surface appearance. If I understand that my character's head is a sphere with a certain proportion of face-to-cranium, I can reconstruct that head from any angle. If I've only memorized what the character looks like from one angle, I can only copy that angle.

The practice that builds this: draw your character from unfamiliar angles deliberately. Three-quarter from above. Three-quarter from below. Pure profile from below. Each unfamiliar angle reveals what you actually understand versus what you've been approximating.

The character sheet as a tool: a complete character sheet with front, side, back, three-quarter, and expression studies at consistent scale serves as a construction reference. Not for tracing — for checking proportions when your construction intuition produces something that looks off.
