Illustration Friday - shadows

Another pencil drawing colored digitally. What will they meet at the end of the passage? I think this pair is braver than I am.
My first thought when I saw the word "shadows" was of Peter Pan dancing and crowing to have his shadow back and since we had a copy of the story illustrated by Alice Woodward when I was young this is the picture I saw in my head - at least this is the best image I could find of it on the web.
