Minimalist Symmetrical Sports Poster

A clean minimalist sports poster featuring {argument name="player" default="a legendary football player"} viewed entirely from the back, standing confidently in the center of the frame. The player wears the {argument name="kit" default="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 {argument name="background color" default="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.
