Off to a good start!

It doesn't matter that you didn't make up this world. Otherwise, nobody would do Middle Earth or Star Wars maps.

Your map really wants titles on the colored areas. Or at the very least a color key somewhere.

Then, are there going to be cities?

Also, I think the texture in the sea needs to go byebye. It makes the continents look like they're laid flat on some weird showercurtain from the 1960s. If the sea texture can't match the coasts, then just use straight blue or some other color (black is cool).

It looks good so far. Please post your updates!
