With the art itself, no, it is rather well drawn.

The issue is with the subject it is based on, namely mlp, which is obnoxious to lots of people, including me. And if you don't tag it as such, we can't filter it out, and get annoyed when it pops up while browsing.

And actually it would also help people who use the search to look for such stuff finding it aswell.

Win win.
