The castle stands tall at the center of the forest, its walls and towers silhouetted against an orange sky. The moon is full, casting a sinister light on the trees below. A small group of people stand in the foreground, gazing up at the castle in wonder, even though they cannot see what lies within. One of the figures holds a staff, its tip glowing brightly, casting a mysterious light above them. To bring this illustration to life, I would opt for dark, earthy tones to paint the forest below. The moon could be silver and shining and the sky a mix of oranges, purples and reds to create a captivating sunset. The walls of the castle could be a deep grey and the pointed towers a stark black. Finally, the staff should be rendered in a warm, golden hue to complete the image.
