You don't need to show them, but also download all the different colour circles and move them onto each region to see how they contrast to your island colours. I see a slight similarity in a few that might cause a camouflage. Keep changing the number on the following link to get all the colour circles. There are 2 oranges I believe, I can't remember which is which, but they are at least the same colour.
http://www.dominating12.com//image/site/large_circles/6.pngI would make those connection lines a little thinner too as well as make them floating as much as the islands (same exact drop shadow). The same with the region names, otherwise you have different altitudes and the brain gets a little confused.
This floating effect might be a problem as all your territory labels are also over the sky area and are shown to be behind the land in distance from the eye. Normally these would be over the land and therefore perceived as the same distance from the eye.
Readability is very important too and single text colour with no outline or shadow usually blends too much giving no real distinction, so either put a thin white (1 px) Stroke on the labels or turn them light in colour with a black Stroke or a Shadow, but then we are back to the floating height, where the shadow will not be doing what you intended it to do, because it will be far away.
Just try to think "stay away from cheesy" with everything you try, until you find what looks aesthetically pleasing.
It is normally best to get depth perception right and true first and play about with the altitude afterwards, using the same height for everything thereafter.
The early tendencies are to make things bright & bold, but in a lot of artistic things 'less is more'.
(Edit) I would straighten the top left connection line to perfectly horizontal, because it is making the map look like it is rotated clockwise or sloping to the right. It is an optical illusion caused by 2 other points of reference (Top map edge & Title) being horizontal and the connection being sloped.
