A potential description could be:
"In a serene lakeside setting bathed in soft, natural light, a group of smiling girls dressed in flowing chitons playfully gather around a young man resting on a sun-warmed rock. The young man, peacefully asleep, is shielded by the girls' delicate hands, which artfully cover his modesty. The scene captures a blend of youthful innocence and joy, highlighting the carefree spirit of summer days by the water."
