A 5 minute video taken from a helicopter as it flew around the island. The helicopter takes off from Ao Nid pier and then circumnavigates the island, following the coastline. You should be able to make out some resorts and will notice some undeveloped beaches, which are worth seeking out when you are there in person.
The guys in the video are the Koh Mak bigwigs, governor of the island and friends. Helicopter tours aren’t available to all. :-)
