The composition is rich with detail, showcasing the textures of both the plants and the bark of the trees. The background is softly blurred, emphasizing the main subjects.

This focus on botanical elements creates a sense of intimacy with nature. The painting is executed in oil on canvas, allowing for vibrant colors and intricate details.
