A professional, artistic audiobook cover design, square 1024x1024. The scene depicts a nostalgic, sun-drenched coastal summer atmosphere. In the foreground, a pair of worn-out leather sandals and a classic sun hat resting on weathered wooden floorboards of a beach house balcony. In the background, a soft-focus, golden-hour view of a calm blue ocean meeting a hazy horizon. The color palette features warm sand tones, deep azure blues, and soft sun-bleached yellows. The lighting is cinematic, casting long, gentle shadows. High-quality digital painting style with a focus on textures like wood grain, woven straw, and water ripples. Ethereal, romantic, and peaceful aesthetic. Absolutely no text, no letters, no words, no logos.
