A dramatic portrait of a young woman with striking features, set against the backdrop of an urban rooftop at twilight. Her expression is confident and contemplative, and her hair is styled in loose waves that catch the last rays of sunlight. She wears a chic, modern outfit with a high-contrast pattern that complements the city lights behind her. The lighting should be soft yet dramatic, highlighting her face with a gentle glow while casting interesting shadows. The color palette should include deep blues, warm oranges, and subtle purples, creating a sophisticated and vibrant atmosphere.
