Create a poignant digital anime illustration depicting a college girl saying farewell in a nighttime park, tears streaming down her face. Capture the emotional atmosphere with soft lighting from street lamps casting gentle glows, highlighting the somber mood. Show the park's serene beauty with subtle details like rustling leaves and distant sounds of the night. Use a color palette that reflects the emotions of parting, blending soft blues and purples with warm tones to convey a sense of nostalgia and longing. Ensure the girl's expression and body language convey her inner turmoil and the bittersweetness of the moment, creating a powerful and evocative scene.
