Um. This is a slightly dark picture, but it's still THERE. Things can be defined in it. If other people can see it and you can't, then it's either one big joke against you, or you've got a problem on your computer.
And in all honesty? I think I've been reading too much web-comics. I saw something different in that until I looked closer.
It strikes me kinda funny that I can see it, actually, since my Danbooru background color is almost the same as that of the image. Makes seeing transparent lineart images hell, but burns the retinas a bit less.
