A professional, high-quality steampunk digital painting of a mature, voluptuous 40-year-old British woman in a revealing, corseted steampunk dress with gears and leather accents. The art style is richly detailed and imaginative, with warm, sepia tones and intricate textures that highlight the Victorian-inspired design and mechanical elements of her outfit. She has shoulder-length, curly, auburn hair styled in loose ringlets, piercing green eyes, and is wearing sophisticated, vintage makeup with dark red lipstick and subtle eyeliner. The setting is a grand, steampunk laboratory with brass machinery, clockwork devices, and cog-laden background under the ambient glow of Edison bulbs. The composition is a front view, capturing her confident, adventurous stance and the elaborate details of her attire, evoking a sense of innovation, elegance, and nostalgic charm.
