This map is going to be scrapped and re-done its awful, i only post it here as an example of what im trying to do, have a laugh at my expense its fine lol.

Basically im working on my own TTRPG and the map is quite a big part of it, when traveling over different areas of the map, the players stats are affected depending on the area theyre in, easy, moderate or difficult terrain for example. i need a way to relay to players what kind of terrain/area theyre in visually on the map. in this attempt i used a slightly see through overlay on the map with different colors representing the area theyre in, but it looks terrible, any other ideas on how to acheive this?
