It's the Spire of Doooom! It reaches up into the skyyyyyyy! It's opening a portal to helllllll! So Satan can screw us with his cooooock!
Okay, I'll stop now. I only drew one of these things, unless this counts as a Spire of Doom. I really need to get back to these fast drawings. Lately, I've been bogged down with fussy details and color experimentation. I think it's getting on my nerves.
