Butterfly floating in the blue night

Subject:
A butterfly floating in the blue night

Main Subject:
In a glass-walled location in the blue night, a woman is positioned alone in the center of the frame, looking up and gazing at a single glowing butterfly floating above, a fantasy-style vertical portrait. There is only one butterfly, floating near the upper right of the face.

Character/Expression:
The face is turned greatly upward, a profile facing right, the pupils also looking up at the butterfly, with a surprised and gentle expression and slightly parted lips. A rounded oval face and small chin, large eyes visible from the side and natural eyebrows, a thin straight bridge of the nose and a rounded tip, pale pink lips. Fair and smooth skin, light makeup. Black hair with short bangs above the eyebrows and a shoulder-length inner-curl bob.

Clothing/Posture:
A white crew-neck sleeveless tank top, with a sheer white long-sleeved shirt worn open over it, and light gray drawstring pants. Hands are lightly folded in front of the lower abdomen, shoulders pulled back, neck elongated.

Background/Lighting:
On the left side of the frame are glass walls reflecting blue lights and horizontal greenish-white light; the background on the right side is a dim passage and bluish-white light spot bokeh. The butterfly serves as a strong light source of purple, blue, and white, casting soft light on the upper part of the face and the pupils. The overall color tone is a cool deep blue.

Composition/Lens:
3:4 vertical aspect ratio, shot from an angle slightly below eye level, a medium portrait down to the upper thighs. The character occupies most of the space center-right, with a small gap between her and the butterfly. Focus on the woman and the butterfly, with the background strongly blurred with a shallow depth of field.

Texture/Style:
Fantasy composite expression based on realistic photography. Detailed depiction of moist glass reflections, thin cloth, skin, translucent butterfly wings, and tiny glowing particles.

Negative Prompt:
Do not make multiple butterflies; do not weaken the upward angle of the face.
