A professional, high-end audiobook cover art, square 1024x1024. The composition features a silhouette of a man and a woman in 1920s formal attire standing on a rain-slicked cobblestone terrace at dusk, overlooking a soft-focus European estate garden. Symbolism: a single withered red rose lying on the wet ground near them, catching a sliver of moonlight. Color palette: moody deep indigos, charcoal greys, and muted velvet reds. Style: cinematic oil painting texture, elegant, atmospheric, reminiscent of classic literature illustrations. High contrast between the dark shadows of the environment and the soft, melancholic lighting. No text, no letters, no words, no title, no author name. Professional aesthetic, clean, sophisticated.
