Escher Dreaming of Cthulhu

For the sake of the new age whatevers, pagan folk metal bands and Cthulhu, here it comes a new red epic nightmare.
As One Escher's triangle wasn't challenging enough I went for three of them :3 Twisted, joined, sick. Yeah, let's add
some lightnings as well, I thought then! xD
This is actually a 3D project, done in 3D Max. I agree 70% is retouch, but still. 3D provided the basic shapes (crossed
penrose triangles) and the masks, depth passes, reflections to make the retouch possible and smart.
A huge thanks goes to the DA community for the brushes I used in this project. If you spot one of your brushes here
consider yourself hugged.
Since I have no idea what this deviation represents you are very welcome to suggest^^
If for any reason you want to print it I have a 5000px wide copy.
