Photorealistic vertical 9:16 dreamy fashion portrait inside

Photorealistic vertical 9:16 dreamy fashion portrait inside a moody Gothic cathedral with tall arched windows. Low-angle shot from below, framed from the waist up. A woman reaches one hand toward the camera holding a small white flower bouquet. Bright backlight outlines her hair, with soft haze, floating bubbles, and sparkling dust in the air. Pale blue-and-ivory flowing outfit, ethereal cinematic mood, shallow depth of field, realistic skin, natural hands, no text, no logos, no watermark.
