Nice timing, good shooting! Congrats!
On this island the moon sets always in a cloud on the sea.
Since we are only 21 degrees off the equator, both the Sun and the Moon appear and vanish very fast, neary vertically. If you want a certain foreground, you have to use Google maps to figure out hot to get it in the picture. There is also an app for Android and iOS http://photoephemeris.com/
that helps you to figure out the heavenly bodies' positions for your shot.
The temptation to copy and paste a moon from another shot sometimes becomes irresistible...I only had the 35mm and the poor Moon looks so small!
Also, if you stop down you get the moonbursts and if you don't you get no DOF.
