Radfahrer auf sonniger Küstenstraße unter weitem blauen Ozeanhimmel

A coastal highway bathed in warm sunlight, a lone cyclist pedals along the bottom, simple modern streetlights line the road, the deep blue ocean stretches above, its sparkling waves reflecting off a clear sky, a massive stylized white cloud dominates the upper frame, a flock of seagulls soar around it, rendered in a vibrant retro illustration style, a minimalist composition, bold flat color blocks, a serene and nostalgic mood, a clean graphic quality, and ultra-high definition.
