Meerjungfrau mit fließendem blauem Haar über einem sonnenbeschienenen Meer

Mixed-media. Surreal, fantastical Art deco artwork in the style of aquatic fantasy concept art. Rearview of a beautiful mermaid with long blue hair sitting on a rock overlooking an impossibly blue sea, golden sunlight glinting off her shape. Art-deco-inspired setting. The image should feel like a vintage mixed-media movie poster, with bold lines, golden ornaments and vibrant, almost magical colors. The overall effect is otherworldly, insanely beautiful and iconic. 8k resolution, high quality.
