Photorealistic Gym Selfie Portrait with Specific Composition and Color Palette

Prompt

A young woman with a slender build and graceful curves, wearing long dark hair in loose waves, is taking a mirror selfie in a modern gym. She is dressed in a striking bright rose-pink athletic outfit, including a tight sports bra and fitted workout shorts, highlighting her beautiful waist-to-hip ratio and fair skin. Compositionally, she stands sideways inside the black frame of a Smith machine, holding her phone up in her right hand, while her left arm is stretched upward to grasp the top crossbar of the equipment, and her left leg is lightly raised, resting her leg line on the horizontal barbell bar. The environment is brightly and evenly lit, conveying a cool industrial feel, with the surfaces of the metal equipment shimmering with crisp highlights. The floor is a dark gray non-slip rubber mat with a subtle granular texture. In the background, neatly arranged barbell plates, orange gym equipment racks, and a white wall with black artistic lettering are clearly visible. The color palette creates a strong contrast between the highly saturated rose pink and the steady black and gray, accented with a touch of orange. The overall image quality is delicate, with distinct layers of light and shadow, presenting a modern, stylish, and energetic fitness atmosphere.
