巨大テニスボールに乗ったアスリート

A dramatic studio fashion-sports portrait of a female athlete reclining confidently on an oversized neon-yellow tennis ball nearly as tall as her torso, centered in the frame. She wears an all-black athletic outfit: fitted long-sleeve performance top, black leggings, black wristbands, black knee-high sports socks with white double stripes and small swoosh logos, and black running shoes with white midsoles and white swoosh logos. Her pose is relaxed and editorial, leaning back with one arm draped over the ball, one leg bent across the top, and the other leg extended downward with the foot touching the glossy reflective floor. Behind her, the word {argument name="headline text" default="GOAL"} appears in enormous bold white condensed sans-serif letters filling almost the entire background wall. The backdrop is a dark emerald-to-black gradient studio background with moody high-contrast lighting, subtle rim light, and a polished campaign aesthetic. The giant tennis ball shows realistic fuzzy texture and curved white seam lines. Composition is square, centered, and minimal, with the athlete and ball overlapping the giant text for depth. The model is {argument name="athlete gender presentation" default="female"}, wearing {argument name="outfit color" default="all black"}, posed on an {argument name="sports ball type" default="oversized tennis ball"}, with the background color set to {argument name="background color" default="dark green"}.
