You got an beautiful seed, this seed contain two survival island but it look like than an large island because two island very close with other. If you don’t like using this beautiful island in survival mode you can create something special on creative mode with this perfect terrain and lots of area to make use of in terms of building. Make sure you can find some great use of it. Like me, I create an house in an island by using the Instant Structure Mod. You can see it in picture below.
