Golem Hall Poster

I CAN'T REMEMBER HOW LONG THIS TOOK ME TO DRAW.

Anyways, here's the poster for my upcoming animation "Golem Hall" ( I got the name from one of the "halls" in our old underground colony on beebscraft )

I really don't know how long this will take me, it will be a full colored animation animated to this song--> [link]

So yeah, try to guess what it will be about :>

I will post a less dark version soon...probably
