I like the sense of characterization in perceptions like “spiteful sunlight” and “optimistic heat.” I’m curious to know what has Emily in such a foul mood!
But it feels wordy, too heavy, like you can express the same ideas more economically. If the whole story reads this way, it might turn into a bit of a slog. Look at slightly awkward, bottom-heavy phrases like “as she marched through a throng of people who were clearly enjoying the weather more than her”, redundancies like “just as annoying, perhaps more annoying,” and two-adjective combos like “hot golden” and “sticky optimistic” and see if you can trim it down.
Thank you Yes, I do have a tendency to ramble on. It's almost as if I can't help myself. It'll be a fun challenge to edit this down and make it less awkward.
