Hey, Rahva! I am giving you REP for posting a map.
I like the coastal design of your continent - not too smooth, but nice and fractalized, more realistic that way.
The technique you're using to highlight the coastal waters seem kind of weird, but maybe its not completely developed yet. I'd say look at other maps here and get a feel to how we make coastal waters.
Separating a continent in half to favor two different gods is not such outlandish concept in a fantasy game - I say continue on that path, it works. And separated by a huge mountain range is proper obstacle in such a world.
I think you'll need to make more, though smaller mountain ranges, as most continents have more than one range of mountains on it. Unless this is a smaller subcontinent.
Anyway, good start and I look forward to your progress with it.
