Create a fusion art portrait that combines a female face with vibrant watercolor splashes and bold ink lines. The face should exhibit expressive features, with a thoughtful or introspective gaze. Use bold, flowing watercolor strokes in bright blues, pinks, and oranges to create a dynamic background that blends with her face. Overlay intricate black ink lines and patterns that swirl around her features, adding an artistic touch. Apply a watercolor effect to soften the edges and blend the colors smoothly. Use frequency separation to maintain the skin's texture while enhancing the boldness of the colors. Add a slight vignette effect to focus attention on her face, allowing the colorful background to create a captivating atmosphere.
