Ivory dress portrait in a sunlit empty auditorium

Create a distinct photorealistic vertical 3:4 cinematic portrait featuring a new fictional, clearly adult East Asian woman, age 21, in an old empty auditorium. Preserve an intimate contemplative scene with a seated figure in the lower middle and tall shafts of daylight descending through the generous space above her. Rows of worn dark wooden seats and curved armrests recede toward the back, creating converging diagonal lines around the figure. The upper wall is aged gray-beige plaster, the lower wall deep muted teal, with a small unlit old wall sconce at upper left.  She perches sideways on the curved back of a wooden seat near the aisle, torso leaning slightly forward, head bowed and eyes lowered toward her lap, lips softly relaxed. Her visible face has a gently tapered adult oval shape, softly defined cheekbones, slender straight nose, natural small lips and elongated dark eyes partially obscured by the downward angle. Long dark hair is loosely parted and braided into one thick braid falling over the nearer shoulder down the front of her dress. A few wispy strands fall beside her forehead and cheek, glowing where the overhead light catches them. Keep a mature adult face, natural head size and lightly refined skin with delicate microtexture.  Her floor-length ivory cotton-gauze dress has long loose sleeves, softly gathered cuffs, a small lace-trimmed V neckline and a relaxed flowing skirt. Preserve the delicate weave and luminous semi-translucent fabric edges in the light while keeping the torso and intimate areas reliably covered with opaque fabric layers. This is an everyday vintage-inspired dress, not lingerie or an evening gown. Her nearer hand presses down on the dark curved seatback beside her hip as a believable support point, fingers curved naturally around the wood. Her knees are bent together toward the right, making a rounded raised fold beneath the skirt; the skirt hangs in long vertical folds below and trails gently across the adjacent seating toward the lower right. Do not invent a visible second hand or bare legs where fabric and angle conceal them.  Give her a delicate, lightweight adult frame with moderately narrow relaxed shoulders, slender arms, a natural ribcage and balanced adult head-to-shoulder proportions. Natural full curves remain subtly suggested by the seated posture and draping fabric, without enlarging, flattening or forcing hidden contours into view. High daylight from the upper left and center forms visible pale shafts in lightly dusty air, a thin halo around the hair, a bright patch across the bent knees, and gentle illumination on the bowed face and nearer shoulder. The auditorium stays deep green-brown and low-key, with restrained soft shadows, worn wood texture, faint airborne dust and realistic tonal falloff. Keep the ivory fabric luminous without losing its woven detail.  Use natural portrait perspective and a slightly elevated three-quarter view, holding the entire relationship of bowed face, braid, supporting hand, raised knees, long skirt and receding seats. Quiet solitude comes from the downward gaze, still supported pose, empty rows and directional light. No added props, lettering, dramatic makeup, exaggerated anatomy, doll-like proportions, artificial glow or plastic skin.
