i have some ideas for when a player is inside the harbor view
Lifeing Harbor
the Harbor and Ship both feel like a ghost town what i could suggest for this is puting in a option to turn on or off people walking around in the harbor or on your ship
Day/Night Circle
a Day and Night Circle as a option to use in harbor view would also work having the buildings with their lights on with search lights watching the horizon or the water
Optional Weather Effects In Harbor
Weather Effects such as fog thunderstorms snow or hurrciances would count as a option seeing Waves from a storm or pockets of ice in the harbor or even fog surrounding the harbor
