I really like how clean and easy to parse your entry is. This is going to be very easy to run at the table, which is what matters most to me about adventures, whatever their other merits might be.
I also like that each encounter has something to interact with.
Nice clean map as well.
I'm not sure about the title font you use throughout. It suggests either a computer glitching out or sand being blown by wind, neither of which really match what's happening in this adventure.
There are also a few typos it'd be worth stomping when the judging period is over.
For next year -- and I hope you enter again next year! -- I would lean more into the weirdness of Appendix N, which isn't really present here.
But overall, this a nice little gameable adventure that would fit in nicely in a River of Night campaign.
