It can be difficult sometimes to tell what a much larger area map is really showing when you start to drill down to try and provide more detail. I often look at things like symbol titles and fill/drawing tool names where there aren't more detailed map notes (and I discovered at least one earlier Atlas map where the map notes were hidden off to one side of the map - by quite some distance, and on a hidden layer; I assume this was before things were standardised to have the text-file map notes attached separately, and as a PDF in many cases).
In the end, it's best to design what seems interesting to you that doesn't contradict whatever was shown on the larger regional map, which pretty much seems to be what you have done!
