Ok, I’m writing this post as a reader, not a pretentious writer who thinks they know everything. I don’t.
There’s a fine line between enough and too much description. Too little and there’s no mental picture for the reader. Too much and you’ve lose me, which also means no mental picture.
As a reader, I would take quality over quantity any day of the week. For instance, with a list of like ten architectural details, my brain shuts down after like three. Whatever sets the room or the building apart from other places is what sticks in my mind. Mood, tone, color, decoration, action, a comparison to something I might have seen in real life.
Think of it as a dream place. When I recall the weird places my brain has conjured up while I’m sleeping, I don’t remember every little detail. I remember the important bits, the character or the feel. Whatever I interacted with directly and how it related to what I was doing. Really, that would apply to anywhere I’ve been, not just in dreams, but dreams are sometimes more like books than reality, I think.
