Create a realistic background image for a bulletin board with a highlighted blank text box for later input. The theme of the image should be “Description of a Park or Garden.” The style of the image should be an illustration showing a peaceful and lush park or garden with vibrant colors and intricate details. The blank text box should be prominently displayed in the center of the image, inviting the viewer to enter text later. The overall atmosphere should exude a calm and inviting atmosphere, perfect for displaying information about a beautiful outdoor space.
