So this is pretty simple but i’ll recommend it anyways.
The only actual pictures we have for some parts of middle earth are from artwork and maybe some Lotr games.
For example Dol Amroth is this mighty castle near the sea or at a cliff or a small island. Either way its in high ground. But when you go there its flat because the terrain generates that way.
What im suggesting is to somehow “fix” the hight of the terrain to match the artwork or something. Like Carn Dum but without it being a fixed structure, just the terrain.
