I love Photoshop. There's nothing in this picture that wasn't in the original. I just chose the bits I wanted to foreground. It's hard to believe, but there's no added color.
I got the picture at a spectacularly handy all-Satan all-the-time copyright-free image page. Thanks, Satanists! It's not what you think; I'd actually Googled for "winged disk" but couldn't find a good picture (there or indeed anywhere else). Luckily Lilith here filled my Photoshopping deficit. She wasn't grey enough and the snake wasn't quite punchy enough, but I soon took care of that.
See? Just not quite there enough in the original.
