A good Character design is one which can be identified by its silhouette alone

The Silhouette Test: Why "Shape Language" is the Secret Sauce of Iconic Design

In character design, high-res textures and complex backstories are great, but they’re honestly secondary to readability.

A truly "good" design is one that communicates identity, personality, and role through nothing but a black outline.
