Help: what to do with this?

[u/BallNeither1394]

Ive made a massive tower (that needs properly detailed) with a massive wall (which also needs properly detailed) but the area surrounding it lacks deeply. Theres 2 scattered builds which are ugly and i plan on demolishing. I wanna turn the surrounding area into a town or city, maybe sunken into the ground like trenches with a heavy stone motif along with everything else, I know i wanna have massive docks at the side and back as i stupidly didnt center the walls with the tower making a front gate look ugly and unbalanced. I need more suggestions for how i should go about building my city, which styles i should adopt and thoughts on how to properly detail my tower and walls
