In a forest, a teeneger boy (blue shirt and green pants halfway down his legs, no shoes, very flowing brown hair), ((Peter Pan style)) and a teeneger girl (dress and blouse in neutral tones almost medieval clothes ), light brown hair at shoulder length, are sitting under a tree. The boy's expression is one of joy, the girl's expression is one of sadness. It's an autumn dark afternoon, dry leaves cover the ground. Very detailed design, Gustave Dore style. The clothes remind us of Grimm Brothers tales
