This is my entry for the Polycount Tower.
It’s an underground wrestling ring, where challengers will face each other until one is left standing to face the Undertaker (or Kane). The Undertaker will be watching by his throne, and the other corner is left open for the crowd or anyone to watch. Challengers can come from the crowd, the entrance, possibly by the green lava, and high above the ring (through a tunnel above ground).
This is a bit of a fan-art of WWE Immortals, a fighting-game with pro-wrestlers, in an Mortal Kombat-type environment, and a cartoon-ish hand-painted scene, that was inspired by the game Epic Mickey.
Side Story: I was working on this the whole time I was in Seattle, WA in 2015, while I was at Vertex Solutions/Adayana Government Group, working on military training simulations. The total opposite of what I was doing for work. Also, aside from the table, ladder, and chair that's by the ring, there's a small Polycount logo on the steel chair.
