Create an image featuring a woman with medium-length hair, standing by a scenic riverbank. She should be facing away from the viewer, wearing a light-colored, oversized sweater. Surround her with a lush arrangement of colorful flowers, particularly purple and pink blooms, framing her silhouette. The background should include a clear blue sky and a distant view of buildings along the river, emphasizing a tranquil atmosphere. Remove any brand names or logos from the scene.
