A glimpse at what I'm working on + cover art concern

So the new fic I'm working on is a non-con Fallout: Equestria one-shot based on an image from Derpibooru with the tag "2786269," and there's a little bit of concern with how I'm going to use it as cover art. You'll know when you see it.

My idea was that I invert the color scheme, but I'm not confident if it will still be allowed on the site still. If you wish to view the inverted version, the link is in the tags (broken up into three separate tags; you'll have to splice the link together).

Let me know if there are any loopholes I can take to use the cover art.
