Features
Decide how much of the design should read as hare, bird, or humanoid before adding outfit details. A clear ratio helps the OC feel intentional.
Use ears and feather accents as the main identity hook so the character stays recognizable even in a small avatar crop.
Plan whether the OC hops, glides, perches, or darts. Wings and hare legs should influence pose rather than sit as decorative parts.
Choose clothing that leaves room for wings, ears, tail, and feather shapes. Outfits should support the creature concept, not hide it.
Define whether the character feels shy, mischievous, guardian-like, feral, elegant, or magical so expression and posture match.
A usable OC suggests how it moves, what it does, and why its mixed traits matter for a game-like setting or profile avatar.
