Sneeky's Map Shop. (Request Map, Get Map)

Hey all,

I've been wanting to make a thread like this for quite a time now, ever since I'd gotten into mapmaking. So, here it is: A thread where you can give me an idea for a map, and I'll make it for you. I'll definitely make maps for TTH, TDM, and CTF, but if you want a map for a custom gamemode, you're going to have to give me the colour codes for any new tiles/objects/NPCs. Make sure you're clear what each item is as well, because if you don't, you could end up with something wonky.

Some of my previous maps made on request:

Spoiler: T3rnary

Request:
Alright. Make a map with the maximum possible height. The sky is dotted with floating islands of various sizes, a large one in the top right and top left corners. The large islands in the top right and top left each have a hall. Below is an ocean that covers the entire ground level of the map. Under the ocean and underground, there is a vast network of tunnels. One hall in the bottom left, one in the bottom right, and one in the middle. Make it.

Map:

*Don't think there's a max height, so I made it like 550 pixels high. Fucking huge still.

Huge backstory, PM me if you want to see it. He made a rough sketch of what he wanted.

Er, this is the end of the post, until I think of something witty/poetic to say.
