Regarding grammar, just a couple of run on sentences.
I do get a sense of awe; I felt feelings reading this, but I struggle with this feeling a lot and I would personally read it and pull out anything you find “clunky” and try to find a more “elegant way to say it”. For example, “slow-growing padding of snow” seemed clunky to me, so it could be something else like “gradually rising carpet of snow” or anything else like that.
I also didn’t understand that you meant salt trucks and garbage trucks at first, but there are no salt trucks where I live, so it could be a lack of contextual knowledge.
Also in “His eyes were drawn up toward the heights of towering mechanical contraption” either make contraption plural or add an article before the word towering (e.g. a, the, one).
I can’t personally find any other parts that didn’t “sound right” to me but you’re the writer so just pull out parts and fix them until you like them, I guess. That being said, reading it too much can make you devoid of all emotions toward the paragraph so be aware of overanalysing.
Hope this helps?^^
