Mejiro McQueen is rendered with a graceful, dynamic silhouette that suggests motion even while displayed. The figure captures her refined equine features translated into anime styling: a sleek, white body contrasted by a soft, gradient mane that flows from pale pink at the roots to a warmer rose toward the tips. The eyes are rendered with a glossy sparkle, conveying determination and poise. She wears a minimal, rider-inspired harness with delicate gold trim and tiny emblem accents that hint at her racing heritage. Her pose favors a forward stride, with one foreleg raised and head held high, balanced by a curved tail and a carefully sculpted base that resembles a portion of a racecourse. The color palette sticks to light pastels and crisp whites to emphasize elegance, while subtle shading adds depth to muscles and feathering on the legs. Finishing touches include a secure base and a gloss-free finish on the coat for a premium display look.
