For Your Own Good, Just Say Yes

Other MLP x South Park crossovers (comics of course!) I made:
Stan Writes A Letter To Princess Celestia: fav.me/d5pp2xg
My Little Kenny: Dying is Magic (Season 1): fav.me/d5sqtz6

"Dear Princess Celestia. Today I learned that I hate parties with ponies. Or scratch it. I knew that all along."

I had to draw South Park characters with outlines because they looked weird next to Pinkie - they would look good without outlines next to show-accurate ponies.

I used 3 vectors made by other people in panel 3 (due to being lazy):
Pinkie's Game by Omniferious omniferious.deviantart.com/art…
Vector-phonograph by MisterAibo misteraibo.deviantart.com/art/…
Slice of Cake by Vectorshy vectorshy.deviantart.com/art/S…

Everything else in this comic was vectored in Inkscape and Ponyscape (a derivative of Inkscape) based on the show assets.
