Tiny Asa portrays Castorice from Honkai: Star Rail in a cosplay costume centered on a white dress. The model wears a crown, gloves, elf ears, and a ribbon, with blonde hair, makeup, and purple eyes completing the character styling. She holds a composed pose against a background of blue lighting, while a butterfly detail is visible on the dress. The portrait focuses on the costume, facial styling, and upper-body presentation, with the cool illumination separating the figure from the surrounding background. The white fabric remains the dominant light area, contrasting with the blue glow.
