Very good! I’m guessing trapped in a trunk, near another body. :) I like how as his senses become clearer, we gain an understanding of what’s going on. :)

I loved the line “thrum of a road beneath me sounds my death toll”. IMHO , this came across a bit choppy; it seemed that some senses were added to conform to the challenge, and not for the purpose of advancing the story.

Very well written, as usual. I thought it slightly stronger at the beginning when the incorporation of the senses just seemed to flow with the story. Good job.
