caption: The image shows a self-portrait of a man with black hair and a blue shirt, painted by Axel Galen. The painting is composed of a variety of colors, including blues, greens, and yellows, and the man's face is framed by a white border. His expression is thoughtful and contemplative, as if he is deep in thought. His eyes are focused on something in the distance, and his lips are slightly parted, giving the painting a sense of introspection.
