The left continent looks rather like a seahorse. Was that intentional? Also, its "tail" appears to be a large crater with a central peak, but something looks wrong about that. Maybe it's too neat? Or that it's filled with land but surrounded by water, even though the floor of a crater is normally lower than the surrounding terrain?
EDIT: And the gap in the rim where it connects to the rest of the continent.
Also, the terrain coloration appears to have been applied ignoring coastlines, making the continents look like cutouts.
And what's the projection? The compass rose suggests a Mercator (straight lines radiating to show constant compass bearing), but the crater is at high latitudes, so if it's actually circular on a spherical world, it won't be circular on a Mercator.
