A boy and a girl are running hand in hand, carrying backpacks, under the crescent moon with stars shining brightly behind them. The background is an illustration of a yellow night sky. They appear to be enjoying each other's company as they walk towards the horizon.

Illustrate a sequence of lunar phases from new to full moon along the top or bottom edge of the design. Render each phase in artistic styles ranging from abstract to realistic, using silver tones against a gradient night sky backdrop.
