Romic National Map

[Azélor]

Your rivers are really wrong. They make crosses everywhere wich mean that your landmass is a bunch of seperate islands. I think it was not your intention so there is a couple of things you can do to improve.

1- lakes only have 1 source of water coming out. It's possible to have more but it's unlikly.
2- river flow downhill making the shortest route to the ocean
3 they only join up when they flow downhill
4- if you surround a patch of land with water it will generaly be considered an island so you should separate them somewhere in the middle
It's possible but rare that 2 important rivers take their water from a near source. But even so, it's just a tiny river at start and it's better to avoid mapping it because it's too small and confusing.

One question : what are the approximate latitudes of your map ?

Other than that, I'm not really a good drawer so I can't give advices.
