character: seiun_sky_(reeling_in_the_big_one)_(umamusume), copyright:umamusume. A bright birthday celebration scene featuring Seiun Sky in a playful mid-shot composition. The horse girl stands cheerfully with whipped cream smudged on her cheek, hugging a multi-layered birthday cake with pink frosting and decorative sprinkles. She wears her signature outfit - a white frilled dress with green accents and a golden horseshoe choker. Her grey hair is styled with a yellow flower clip, and her horse ears perk up excitedly. Behind her floats a cluster of pastel balloons and party streamers in soft pinks, blues, and yellows. The entire illustration uses simplified geometric shapes, flat colors with minimal shading, and clean linework to create a stylized, modern aesthetic. Her blush-filled cheeks and sparkling blue eyes radiate youthful joy.
