There are so many 30 day challenges out there it's hard to keep track of them all, but if you've got a black metal heart and a fetish for facepainting the only one you should care about is the 30 Day Corpse Paint Challenge.
And if you want to see a prime example of how to do this challenge right you've gotta watch Modern Valkyrie's "metalhead fantasy-nerd" Lady LeananSidhe kill it with 30 different dark looks that will keep you up at night.
Here's a process video showing Lady LeananSidhe creating her corpsepaint look for day 6 of the challenge- Drama Corpse. And you can see LeananSidhe apply all 30 of her corpsepaint looks here.
