I think the stretched out island looks fine on a globe. I took the liberty of taking your map and put it on a globe (type in 'map to globe' in google and click the first result). In the attached image you see the island in the red circle.

If your not comfortable with me posting this image, just let me know and I'll remove it.

This map looks nice so far, looking forward to see where you take this (:
