It absolutely depends on your aesthetic choice. Our world had maps like this:

Nobody will actually use that map to navigate a world. If you want to convey a sense of awe for the mountains and forests, or a feeling of the world mostly an unexplored, mythological space, I would say it's fine to build it like this. If you want a more grounded, lived-in world, making the features smaller would help it.
