The map is Royal Palace by Zyph
The map is Oasis of the sea by littlesteelo
Feel free to review or ask anything and I'll (try) to answer. Also yes, this is a copy-paste of a post I've done in Minecraft Forums if you've seen it. Don't worry I'm not stealing. You can see more of these rendered on my DeviantArt (Shameless advertising ploy!)
