I think it looks fine. Apart from the colored pencils (I hate trying to color in oceans with them) I see nothing wrong with it all. The shape is cool and the terrain is fine. For coloring oceans I used to rubber cement the landmasses (painters use something called frisket but I only had rubber cement), then water-color paint the ocean with a big brush, then when it dried you rub off the cement (it makes these little rubber "boogers") and do the line work on the land. You need a heavier paper, though - standard paper shrinks and curls with water and combined with the rubber cement staying in place things get warped. Once you browse through the finished maps section you'll find all sorts of new terrains to add and ways to do them. So, all in all, a very fine piece.
