提示詞

A clean minimalist sports poster featuring a legendary football player viewed entirely from the back, standing confidently in the center of the frame. The player wears the Portugal national team home kit with a deep red jersey, green shorts, red socks, and modern football boots. The jersey displays "RONALDO" in gold lettering with the number 7 beneath it.
The composition is perfectly symmetrical with the player occupying the lower-middle portion of the canvas. A smooth sky-blue gradient background fills the entire scene with large negative space above the subject, creating a premium wallpaper aesthetic.
Behind the player, enormous bold white typography spelling "RONALDO" stretches horizontally across the lower background, partially hidden by the player's body.
A dramatic long shadow extends diagonally across the ground, adding depth and cinematic atmosphere. The lighting is soft yet directional, creating subtle highlights on the jersey fabric and realistic folds.
Ultra-clean composition, modern sports branding style, high contrast, crisp edges, hyper-detailed fabric texture, realistic proportions, studio-quality lighting, premium poster design, centered composition, vertical smartphone wallpaper, 8K quality.
