Children’s book cover illustration, square aspect ratio: A small, round brown bear cub with friendly eyes walking alongside three friends under a glowing full moon in a gentle nighttime forest. The friends are: a tiny glowing firefly with a warm yellow glow, a wise owl with calm eyes flying above, and a cheerful green frog hopping nearby. In the distance, a soft, warm light hints at a cozy cave home. Use soft pastel colors (muted blues and greens for the night, warm yellows/oranges for the glow), flat/vector style, simple shapes, and friendly expressions. Leave an uncluttered area at the top for the title text. See more
