Portrait of a serene young model in Alphonse Mucha Art Nouveau style, intricate black lace veil draped over her head and shoulders with elaborate floral and ornamental patterns, white flowers tucked into her curly golden hair, golden halo like circle behind her head, highly detailed ornate background with swirling motifs and geometric patterns in gold and muted tones, delicate face with subtle makeup, ethereal and elegant, masterpiece, ultra-detailed, soft lighting.
