The quote in the middle of the page sorta interfeired with the immersion, just not enough to break it. I have found two SPaG errors, but that is about it. I would have advised against contractions here, but I suppose that depends on stylistic choice in this case.
Overall, a solid piece of writing.
Edit: I would like to clarify that these aren't exactly the smallest of issues; my upvote, in fact, was slightly hesitant.
