The painting is done in a realistic style, with the oak tree standing tall and proud in the center of the field, its branches reaching up towards the sky. The people in the painting are gathered around the tree, looking up at it with admiration and awe. The sky is a deep blue, with a few white clouds scattered throughout. The sun is setting in the background, casting a warm orange glow over the scene.
