Most time I've ever spent on a piece, I think. I mean, I didn't actually keep track, but I started it earlier last month. Also, first time I've ever saved a WIP animation.
I started it with the goal of getting a #1 monthly spot on PJ, but then people started submitting all this awesome stuff within the last few days/weeks. Still, I'm pretty happy with the final result.
Inspired by the song of the same name, by the band of the same name. That, and there's some Dark Tower in there too. Probably a lot of Dark Tower.
