Romantic Short Story Book Cover Design (Featuring gradient, rose, and binary code)

A radiant, swirling vortex dominates the background, merging Klein blue and rose gold in a transcendent gradient resembling a cosmic whirlpool. At the heart of the vortex, a shattered mechanical gear-watch floats midair, its cracked face sprouting a blood-red rose that defies artificiality. Between the gears, faint stardust particles shimmer and flow, creating glimmers of light like pixels dissolving in space. The upper-left corner features a subtle, ethereal sunburst where the hand-sketched Chinese title "时空旅恋" is delicately embedded. A series of pixelated ginkgo leaves and binary code drift like dissolving memories in the bottom right corner. A Möbius strip entwined with a glowing DNA double helix hovers faintly at the bottom edge, semi-blending into the vortex.

The main title, "时空旅恋," utilizes sharp, polygonal, metallic lettering styled to emulate gleaming chrome. Each character is lined with soft, neon-hued (gradient #FF3864 → #2DE2F2) edges for a futuristic glow. The title layout is slightly angled with an upward tilt to mimic forward momentum. The author's name, "银子," is minimalistic and rests at the bottom in clean, sans-serif font, contrasting softly against the dominant imagery.

The overarching composition radiates from the central theme, the vortex. The shattered gear-watch and blooming rose sit at the center, commanding attention. Accompanying elements like the hand-written Chinese title align toward the top-left, balancing the dominant middle. The lower-right details of pixelated silver ginkgo leaves and binary codes serve as a counterpoint for weight and depth. The Möbius strip and DNA thread subtly layer over the background gradient at the bottom edge, seamlessly integrating into the vortex design.
