Celestial witch portrait from a selfie: moonlit forest, glass orb
Prompt for Gemini: turn a selfie into a moonlit witch portrait with a star-map gown and a dim glass orb, face kept intact.

The prompt
Use the uploaded photo as the only reference for the face. Keep the exact facial features from the uploaded photo: same face shape, same eyes, same nose, same mouth. Do not smooth the skin, do not change the age, do not slim the jaw. SCENE: a night portrait in a [FOREST TYPE: birch] forest, the subject turned three-quarters to camera, ground fog to knee height, a full moon low behind the subject. WARDROBE: a [GOWN COLOR: deep indigo] velvet gown with fine silver thread embroidery in small star-map patterns across the shoulders and sleeves; a soft felt pointed hat, brim tilted back so both eyes stay lit. LIGHT: two sources only. A cool moon rim light on hair and shoulders from behind. A [ORB COLOR: pale blue] glass orb held in both hands at waist height, dim like a night light, lighting the hands, the chin and the underside of the brim. Everything else falls to near black. CAMERA: 85mm lens, f/2, camera at chest height, background blurred by shallow depth of field, vertical 4:5 frame cropped just below the hands. EXPRESSION: [EXPRESSION: calm and watchful], mouth closed. CONSTRAINTS: photographic, not illustration. Keep skin pores visible. One moon, one orb. No glitter particles in the air, no floating symbols, no lens flare. Both hands complete and inside the frame.
What you get
What you get: a vertical frame that runs from the top of the head to just below the hands, almost monochrome. The background is a wall of dark birch trunks, gray-blue, with fog lying at knee height. The moon sits low and slightly left, so a thin cold edge of light runs along the hair and the top of the shoulders. The only other lit area is the lower face and the hands, lit from below by the orb: chin, jawline, the inside of the hat brim. Silver embroidery on the shoulders catches the moon and reads as small broken lines, not as clean stars. Skin keeps its texture, pores visible in the cheek light.
Where it breaks. First, the orb burns out. Gemini treats any light held in the hands as a bright one and turns the glass into a white blob that eats the fingers. The words "dim like a night light" are in the prompt for that reason; if it still blows out, add "the orb is barely brighter than the moon, keep detail inside the glass". Second, the face gets younger. The model smooths pores and thins the jaw even with the face clause in place. Do not retype that clause louder. Keep the generated image in the chat and send a correction turn: "compare with the uploaded photo and restore the original face, keep the pores and the fine lines, no retouching". A source photo at least 800 px wide across the face, evenly lit, makes this land on the first try. Third, the eyes go dark. Backlight from the moon plus a light source below the chin leaves two black holes under the brim, even with the brim tilted back. Raise the orb to chest height so the light reaches the eye sockets, or drop the hat and use a hooded collar. Do not paste Midjourney flags here — Gemini ignores --ar and --no; write "vertical 4:5" in words.
