A professional, high-quality watercolor painting of a mature, voluptuous 40-year-old Persian woman in a luxurious, revealing traditional Persian dress adorned with intricate gold embroidery. The art style is soft and luminous, with delicate brushstrokes and rich hues that highlight the opulence of her attire and the elegance of her form. She has long, wavy, jet-black hair flowing freely, captivating hazel eyes, and is wearing subtle, classic makeup with a deep red lip and kohl-lined eyes. The setting is an ornate, historic Persian courtyard with intricate tilework, a flowing fountain, and lush greenery under the gentle glow of lantern light. The composition is a front view, capturing her poised, regal stance and serene expression, exuding grace, cultural richness, and timeless beauty.
