Art Nouveau Tempera and Gilded Leaf Portrait of Mantle Dane

Full prompt

An Art Nouveau tempera and gold leaf painting in a 1:1 square aspect ratio portrays a noble mantle Great Dane within an intricately stylized decorative framework. Centered harmoniously within the square canvas, the hound stands in proud three-quarters profile, its glossy black coat and white chest, muzzle, and neck collar defined by elegant organic lines and natural drop ears. An ornate circular halo of raised 24-karat gold leaf swirls around the canine's head, filled with stylized irises and scrolling acanthus foliage in the decorative manner of Alphonse Mucha. Subtle mosaic motifs in peacock teal, burnt sienna, and warm parchment fill the background corners, marrying rich matte tempera textures with gleaming gilded brilliance to celebrate the dog as a mythic guardian.
