This world is just generally a desert, if this is what you need for your build, that's good, but keep in mind there's a lot of caves.
There's not much I can really say about it, other than that the islands to the west, are mostly badlands and such, and the main island is all desert.
There's not really much creativity you can have when making a desert.
