Point is, this is not a complete map of the world, because folding it together would not form an orb. You could make it look a bit more like, when exiting one side of the screen, you reenter through the other side. If you look at every map of the complete world you'll ever see, you'll probably notice that there aren't any continents that are only depicted HALF (notice your most right continent? If anyone in your world would sell your main character half a map, you should let him get sued.)
That sounded a bit too negative, that last thing. The top of your map (the antarctic bit) is quite correct, and upon walking past that, you should under no circumstances be able to appear on the other side of the map (which does happen in some games and is, just technically impossible.)
But you've got a decent thing going on, it's just that it's not a complete world and you'd have to finish that Eastern continent, that's what I think.
