After a while of working on the map, I have finally finished it.
This is CTFM-Triton, a 3 team Multi-CTF map. It's an orbital station orbiting Neptune. For the skybox, I took inspiration from CTF-Face, except this skybox has Neptune and Triton as opposed to Earth and the Moon. For the map overall, I went for a sci-fi style and textures from the Coret_FX and PlayrShp texture packs are heavily used.
Here's an in-game screenshot:

Attached is a .zip file containing the map and everything required for it to work.
