Create an ultra-realistic sky scene where soft, natural cloud formations organically assemble into the clear silhouette of a heart. The cloud shape appears high in a vibrant blue sky, naturally floating above a recognizable nature below. The composition is square (1080×1080), with the cloud formation occupying the upper portion of the frame while the landscape grounds the scene beneath it. Lighting is crisp and daylight-bright, with sunlit highlights on the clouds that enhance depth, softness, and realism. The overall mood should feel calm, optimistic, and visually striking, with rich color saturation and a clean, peaceful atmosphere.
