Art Nouveau Botanical Portrait Prompt

Create an elegant, richly detailed Art Nouveau portrait, vertical 4:5, for a written subject in a graceful pose. Build the likeness from accurate facial construction — individual proportions, eye spacing, eyelid shape, eyebrows, nose, lips, cheekbones, jaw and skin tone — rather than generic beauty, and keep the face fully visible and unobstructed. Style the hair as elegantly arranged flowing sculptural curls and ribbon-like strands, weaving peach flowers, sage leaves and fine gold accents naturally into the arrangement. Dress the subject in elegant fitted clothing with embroidered botanical details and softly draped fabric. Build a fully designed Art Nouveau environment around them: flowing vines, floral scrollwork, curved geometric borders, delicate filigree and embossed botanical surfaces, with a circular ornamental halo behind the head where the composition allows. Use a controlled palette of soft mint, sage, muted teal, warm ivory, cream, peach and antique gold, soft diffused light, crisp botanical linework and refined, richly illustrated finish.
