The subject was to draw something related to the Apocalypse, any style. I tried to play more with the Darksiders style, and since I loved the horse design I did my own with the fourth horse.
The rider is random, is not based on the game (I still haven't played it or even seen more than some trailers).
I liked the creature, which it's totally based on the writings in the apocalypse book.

"The horseman was in the wrong place when the beast suddenly awakens from its long sleep, emerging from the wild sea. His faithful horse rears fiercely to face the menacing seven-headed creature in order to protect his rider.
The end is near and the only way to beat this apocalypse lies in the light beyond"

That's the scene I liked the most (the beast emerging) and thought it would fit my style. I added the horse because I love horse. And the rider..Because the horse of the End of Days needs a rider =P

Hope you like it.
