Return of the Devilish Door

About 2-3 years ago, I invented a dark-toned story, a sort-of metaphoric autobiography. In this story, the main protagonist first had to choose between the door to his own normal world, and the Devilish Door, which leadt him to the other world, a tortured world coming straight from his head. Some viewers remind the old Devilish Door ([link]), well this is a remake, and it could be in a possible follow-up of the story. The main protagonist might come back and retake the door, but this time with 3 heads and more parts, because the other world is only darker and darker.

So I guess that's pretty much. I've done the entire drawing by my hand, and it took me about 3-4 hours for every details. But the color was put with Photoshop, the original drawing is black and white.
