I liked “Trees thinned ahead” that is such a precise use of language and it places a perfect image in the flow of the story without making a splash, or missing a beat, if you will.
I enjoyed this story for its flashes of brilliance but I think your opening could improve if you consolidated the sentences.
For example:
“The leaves crashed too loudly as Niccolas ran. He tried to minimize…”
Telling us that the leaves will give him away takes away from the suspense. We know right up front that he gets caught so why keep reading? I suggest letting the descriptions show us how vulnerable he is instead.
There is potential here for an engaging story, and I know you are more than capable. I like your writing.
