Create an anime-style 3D head-and-shoulders avatar of an original fictional adult {{gender}}, age 27. Appearance: {{appearance}}. Expression: {{expression}}. Use a clean {{palette}} palette, simplified clothing, softly sculpted hair and clear eyes. Center the face with a straight camera angle and gentle diffuse light. Keep the entire head, hair and shoulders within the central 75 percent of a square canvas so a circular crop will not cut important features. Use a simple solid {{background}} background. Make the expression readable at small display sizes. No text, decorative border, logos or watermark.
