Portrait lumineux d'un papillon dans la nuit bleue

【GPT Image2 Prompt】 Subject: A butterfly floating in the blue night Main subject: In a glass-enclosed space on a blue night, a single woman in the center of the frame looks up at a glowing butterfly floating above her head in a fantastical vertical portrait. Only one butterfly floats near the upper right of her face. Person and expression: A right-facing profile with the face turned largely upward, eyes raised toward the butterfly, lips slightly parted in a calm expression of surprise. A rounded oval face with a small chin, larger eyes visible from the side, natural eyebrows, a slender nose bridge with a rounded tip, and pale pink lips. White smooth skin with subtle makeup. Black hair with short bangs above the eyebrows and a shoulder-length inward-curled bob. Clothing and pose: A white scoop-neck tank top, layered with a sheer white long-sleeve shirt worn open at the front, and light gray drawstring pants. Both hands lightly folded in front of the lower abdomen, shoulders pulled back, and neck stretched upward. Background and lighting: On the left side of the screen, a glass wall reflecting blue lighting with horizontal green-white light; on the right side of the background, a dark corridor with pale blue bokeh orbs. The butterfly serves as a strong light source in purple, blue, and white, casting soft light on the upper part of the face and the eyes. The overall tone is cold deep blue. Composition and camera: A 3:4 vertical medium portrait capturing down to the thighs, from a nearly level viewpoint slightly below eye level. The person occupies a large area from the center to the right, with a small margin of space between her and the butterfly. Focus is on the woman and the butterfly, with the background heavily blurred by a shallow depth of field. Texture and style: A photorealistic photographic base combined with fantastical composite expression. High-definition rendering of wet glass reflections, thin fabric, skin, translucent butterfly wings, and fine glowing particles. Negative: Do not make multiple butterflies; do not reduce the upward angle of the face.
