Gesture, stance, nuance, and the way information is framed is key to how we interpret characters. They are the building blocks through which we consume visual information, which can also entail even more hidden information. A curl of the eyebrow, or a dimple that forms from a smile can be of immense importance to the way we interpret our reality.
One of the goals of a thoughtful, powerful character design is to build a sense of culture, structure, movement, and depth, even using only a few visual elements, carefully presented. An issue with weaker designs is they tend to be loaded up with artifacts that don't have any particular meaning. This is what causes characters to come off like hollow imitations or impostors. A strong design should use such elements carefully, intertwined with narrative, culture, language, and personality, causing each to scale into something stronger than the sum of its parts.
For example, perhaps a gesture is actually a reference to something external: an event, a feeling, or an idea, which is a reference yet to something else, creating a feedback loop, and a structure of associations...
If this is the case, how much information is still hidden beneath the surface of the reality we purport to know? What are the untold stories of triumph, or perhaps atrocity, imbued within this crest, and therefore the gesture?
