I've been working on doing nitty-gritty editor revisions of my detective novel in preparation for publishing, going over sentences and picking through details. In the course of the story, the detective visits a variety of locations in the setting of the story to interview witnesses and gather evidence about the case, most of them within the city where he lives; think a Hercules Poirot kind of "traveling detective" narrative. He typically visits one or two settings per chapter and spends enough time there to get acquainted with the locals and talk to a few important characters - that is, he doesn't deeply dive into each place, but you do get a feel for how each place looks and feels as he explores them.
Recently, I received some editor feedback that the settings needed to be better distinguished from each other - that is, I have to do a better job of making each place "feel" different from each other. She pointed out, for example, that while I do a good job of writing the sensory details of each place, the places need to stand out from each other better in terms of how I describe them and how my POV detective experiences them. To quote her feedback:
You do an excellent job of describing these places, but the Amish settlement comes across similarly to how the diner or the strip club comes across, and I want you to make those immediately distinguishable in that first impression he gets when he walks in. What's weird about this place? How does he get struck by this place as opposed to that place he visited last chapter? What just grabs him and slaps him in the face about it? They have to feel really different and memorable.
I've been mulling on this feedback for a while, and I decided it would make a really interesting question to ask this site for advice, so here is my question:
How do you clearly and immediately distinguish settings from each other, and make them more memorable? What are some prose tactics for achieving this?
