Fierce Focus: A Champion's Sprint

Create a striking portrait of a female athlete, Caucasian, exuding strength and determination. She has high cheekbones, a strong jawline, and piercing blue eyes that reflect focus and intensity. Her hair is pulled back in a sleek ponytail, showcasing a few sweat-drenched strands that highlight her dedication. Capture her in mid-action, perhaps during a sprint, with a slight smile of exhilaration on her lips, conveying both joy and fierce competitiveness. The lighting should be dynamic, with sunlight casting dramatic shadows, enhancing her muscular physique and the contours of her face. Use a shallow depth of field to blur the background, focusing on her, while incorporating elements of a sports field. Render in a hyper-realistic style, reminiscent of contemporary sports photography, with vibrant colors that evoke energy and movement. The composition should be slightly tilted to suggest motion, using a 50mm lens perspective for an intimate yet powerful portrayal.
