Indeed. I suppose the question is of the utility of a map to a reader from our world, as opposed to a map from a fictional world functioning as an artifact from it. My own fontmaking (ugh, kerning), conlanging, and even mapmaking skills aside, I think that this style of map can work.

Now, would it be possible, even now, to re-do this map in a Latin script, and therefore probably improve it aesthetically? Yes. But, in my opinion, it wouldn't function as well as an artifact of the culture I am attempting to create.
