Wow, where do I even start with this one? Well, I guess first off, I've been wanting to do a wallpaper of these two for a long, long time now. The problem was actually *finding* the right images. Seriously, for all the Owari no Seraph images out there, it seems like the Ferid and Crowley ones are lacking for some reason. When I finally ran across the Crowley image, an idea popped into my head for it, although that led for searching and searching for an image of Ferid to go with it.
Long story short, once I had the right images, I ended up deciding that I wanted to do a night theme with them, considering that they are vampires. After much playing around, I finally came up with what I wanted to do with the moon in the sky and clouds to make it more 'mysterious'. Putting this all together once I had all of the pieces I needed ended up taking a little over three hours, but it was worth it for the fact that it actually turned out better than I'd originally thought it would.
