This is a scene of a man standing before a group of people, speaking from a book held in his hands. The backdrop is lush with tall trees, rolling hills, and distant mountain peaks. Various shades of green would be appropriate for the trees, hills, and mountains, with perhaps more vibrant shades capturing the light of the sun. The figures of the man and the people could be given shades of golden yellows, purples, and blues - to make them stand out in contrast to the peaceful setting. For the sky, adding a range of lighter tones from blue, to pink, to white would make the scene truly come alive.
