Potret Anime dengan Cahaya Kosmik Ganda

Vertical digital painting portrait of a young woman with [long messy black hair], turning her bare shoulder toward the viewer while looking back over it with a soft, melancholic expression. Her face is close-up, delicate and luminous, with flushed cheeks, parted glossy lips, fine eyelashes, and large reflective eyes with tiny star-like multicolor highlights. Strands of windblown hair drift across her face and eyes. She wears a simple, mostly hidden black sleeveless top. The background is an abstract cosmic darkness filled with energetic paint splashes, glowing particles, and nebula brushstrokes, split between fiery red-orange light on the left and deep electric blue-violet light on the right. Dramatic dual rim lighting with warm red on the left side and cool blue along the right shoulder and hair. Dreamy cinematic anime-realism style with rich painterly brush texture and high contrast. A small elegant artist mark in the bottom-right corner includes the date "[July 23, 2026]" and the handwritten signature "[Oyagi]". No other text, frame, or watermark.
