It feels like "I am not good at describing things" is the recurring hangup in the Cohost Writer's Salon, and I am not at all joking when I say that I used to worry about it in my own writing, a lot, and then I Just Stopped. (Glossing over a bit, maybe; joking, no.)
My side account on here is called Impressions of Detail, a not-really-prompt account that aims to post something evocative daily. The name speaks directly to my theory of description: that generally, you're aiming to convey an impression, not give a feature rundown. Being told that there are buildings on all four sides of your viewpoint character, all at least twenty stories tall, is qualitatively different to saying they're boxed in and looked down on by window-striped hulks.
If you're describing enough to follow the narrative, everything else is stylistic. Which is not unimportant, but it's also yours to play around with. There's a thing I do in a lot of my current writing, where I talk about some particular thing very specifically — the takeaway meals in The Ink-Coloured Mouse, for example, all consist of specific foods, or Elena the Progress warlock's clothes — and those details, I hope, help to anchor the piece overall in peoples' minds, even as the level of detail I give about other things in the same piece is wildly less — how many of the characters, across the entirety of The Ink-Coloured Mouse, have I given a hair colour at all? It's stylistic! It's characteristic of me, of the things that, given a story, I think are worth picking out to convey an impression of.
If you're getting your story across, your technique might not be what you'd like it to be, but it's not wrong.
