Luxury Sunset Letter Portrait

Create a cinematic luxury typography portrait poster with a warm sunset aesthetic. A vertical 3:4 poster shows {argument name="character name" default="a serene young woman"} standing outdoors by a calm lakeside at golden hour, softly backlit by a low sun on the right. She has long flowing {argument name="hair color" default="chestnut brown hair"}, closed eyes, a peaceful slight smile, natural makeup, and glowing warm skin. She wears an elegant cream embroidered dress with sheer sleeves and delicate floral detailing, holding a large bouquet of tiny white baby's-breath flowers close to her chest. Use shallow depth of field, cinematic amber-orange color grading, soft haze, dark blurred clouds and water in the background, rim light on her hair, and a dreamy high-fashion editorial mood.

Overlay a huge translucent outline serif capital letter {argument name="large letter" default="P"} across most of the portrait, centered and extending from near the top to near the bottom, with thin glowing ivory lines and transparent interior so the portrait remains visible through it. Add top typography reading {argument name="top word" default="LETTER"} in widely spaced elegant white serif capitals. Add bottom typography reading {argument name="bottom word" default="PORTRAIT"} in widely spaced elegant white serif capitals. Include exactly 1 decorative sunburst line motif to the left of her head and exactly 3 small white outline heart doodles near the lower right side. Keep the composition luxurious, minimal, romantic, and poster-like, with no watermark, no extra text, and crisp professional photo-realistic detail.
