The only real problem I see is the map itself. Is it a world map? If so, the north and south frames should be longer than the east and west frames. That should help solve the spacing problems.

Otherwise you could simply expand the map size (not the map itself) and then move the islands allittle further away from one another to reduce the cramping effect.

All in all, great start, though. Alot better than my first (or even my current) maps.
