Tribal shacks - The Goby Riders

Very late for the "Tribal Shacks" contest @ Conceptworld, went to Holland for ten days... oh well, another scene from my game idea. I'll try to submit to environs anyways...

This is a scene from a planet covered entirely by water, the original colonists on the now heavily populated planet known as "the locals" are now a tribal pirate-like race, preying on straying fishing vessels, killing the crew members and cannibalizing the ships to create new strange "shacks". The large pod pictured is one of the original colonies, rusty, but still floating! The locals are never able to breath the atmosphere, and are bound to their suits... however this allows them to utilize the local wild-life to stealthily scout the waters, and are able to stay underwater for short periods of time. They guard their colony locations with their lives, and live comfortably off the sea.
