Photorealistic Gym Selfie Portrait with Specific Composition and Color Palette

A young woman with a slender figure and graceful curves, with wavy dark long hair, is taking a mirror selfie in front of a mirror in a modern gym. She is wearing a set of eye-catching rose pink sportswear, including a tight sports bra and tight sports shorts, showcasing an excellent waist-to-hip ratio and fair skin tone. In terms of composition, she is standing sideways within the frame of a black Smith machine, holding her phone up with her right hand, stretching her left hand up to grasp the top beam of the equipment, and lightly lifting her left leg, resting the line of her leg on the horizontal barbell. The environmental lighting is sufficient and uniform, presenting a cool industrial feel, with the surfaces of the metal equipment reflecting cold highlights, and the floor being a dark gray non-slip rubber mat with fine particles. In the background, clearly visible are arranged barbell plates, orange fitness equipment supports, and a white wall with black artistic lettering. The color scheme features a strong contrast between high-saturation rose pink and calm black and gray, supplemented by a few touches of orange. The overall image quality is delicate, with distinct light and shadow layers, presenting a modern, fashionable, and vibrant fitness atmosphere.
