Yo lads and lassies, been playing around with random seeds for the past few days and have found quite arguably the most awesome (or awful depending on your perspective) seed for starting out in a 'survival island' type map.
First suggestion: Always use default textures when sharing a seed. Otherwise it's hard to tell what we're looking at.
A good survival island should have at least one tree, otherwise you will need to go off the island in order to actually survive.
Not to be harsh, but I have no idea why you think this seed is "awesome". I would suggest trying out some of the survival island seeds in other threads in this forum. Many of them actually are awesome.
