高訂運動海報：網球員身著白裙，於巨幅「FOCUS」字樣前擺拍，倒映於鏡面地板

提示詞

A high-fashion sports editorial poster on a clean off-white studio background with the word FOCUS in enormous ultra-bold black condensed sans-serif letters filling nearly the entire backdrop from edge to edge. In front of the text, place a tall athletic female tennis player in a confident power pose, full body centered slightly right, with one leg straight on the floor and the other knee raised and resting on the handle throat of an oversized tennis racket standing upright. She is looking to the side with her face turned away, sleek dark hair pulled into a low ponytail, glossy skin, long toned legs, and a luxury campaign aesthetic. Outfit: a fitted white sleeveless V-neck tennis dress with a short pleated skirt, white wristbands on both wrists, white mid-calf sports socks with a black P logo, and white tennis sneakers. The tennis racket is white with a dark string bed and leans vertically under her raised leg. On the reflective black court floor, show exactly 5 scattered white tennis balls, each with a small black P mark, plus strong mirror-like reflections of the athlete, racket, text, and balls. Add crisp white court lines crossing diagonally near the bottom foreground. Lighting is soft but directional studio lighting with polished highlights on the skin and outfit, creating a premium luxury-athletic advertising mood. Minimal color palette: black, white, warm skin tones, and subtle gray reflections. Composition should feel like a fashion campaign poster, clean, graphic, bold, and striking.
