Thank you for your feedback ! 
It's a Map Alpha 0.1, i'm still on the subject and any suggestions are welcome.
There will be several islands, I was thinking 3 or 4, and why connect this map to Sandus Keyes
There will be points for loading and unloading, and of course houses
Two entrances/exits from Los Santos and Angel Pine, one entrance from Flint, one exit from LS Airport
