Prompt: A softly lit reference sheet showcases Hikari "Kari" Aoyama, an 18-year-old with a gentle, almost ethereal presence. He stands in a full-body pose, his delicate features and heart-shaped face framed by shoulder-length ash-brown hair styled in two low pigtails, each adorned with a pale-pink ribbon. Kari’s wide, doe-brown eyes hold a wistful expression as he gazes slightly downward, a subtle smile playing on his lips; smaller inset views highlight this expression and his ink-stained fingertips gently holding a sketch pad filled with manga girl drawings. He’s dressed in a cream lace blouse tucked neatly into a pleated navy skirt, complemented by thigh-high socks, classic Mary Jane shoes, and a delicate ribbon choker, completing his feminine and artistic aesthetic. The clean, flat reference sheet layout is set against a soft pastel background, presenting a detailed and charming anime illustration. Model: GPT Image 2 v1
