I agree with haribo about overlay density, at least judging by the available pictures. their usage is fine, just that having more than one warning, notice, advert sign, etc. per wall can distract attention. just something to consider.
edit: also the theming of the overlays and the companies/areas they represent are a bit awkward. blu industries, husky acres, grey gravel co, something nugget, mining, sea side, mine tours, coal, Mann co. etc.
So the setting of your map is that it is a mountainous facility of sorts that has grain silos and produces or manages grains, manages gravel, does mining, is a coal mine, has direct train access for shipping, and is also a Mann co facility?
