Serene Sailboat Between French Dunes

A serene coastal scene on the French Atlantic coast: turquoise sea under a pale blue sky, with a lone sailboat gliding across the water, its white sails catching a gentle breeze. In the foreground, rolling sandy dunes frame the view, tufts of dune grass waving in the breeze, the warm beige sand contrasting with the vivid turquoise water. The horizon is calm and distant; the light is soft and golden, suggesting late afternoon. Colors are vivid yet harmonious: turquoise and aquamarine waves, light azure sky, and warm sand; overall mood tranquil and dreamlike. Rendered in photorealistic, high-detail style with cinematic lighting, natural textures, and shallow depth of field to keep the sailboat and dunes crisp while the far shore recedes into gentle haze.
