A man stands on a rooftop at dusk, the sky painted with hues of orange and blue, transitioning into the twilight. He is dressed in a white lab coat over a light blue shirt, suggesting a scientist or researcher. His hands are occupied with a smartphone, perhaps checking data or communicating. The cityscape stretches out behind him, with buildings silhouetted against the vibrant sky. To his side, a table holds a small, sparking device, hinting at some form of electrical experiment or demonstration. The scene is a blend of urban life and scientific inquiry, capturing a moment of focused activity against the backdrop of a beautiful sunset.
