This skit is loosely based on this clips from My Little Pony: Friendship is Magic, where Gilda the Griffin makes Fluttershy cry: ([link]). It's sorta a re-match, but with a twist.
Some of this comic is drawn from scratch in Photoshop using a mixture of brushes, layers and vectors. Other components have other sources, which I have favorited and linked to below.
The ponies are based on images generated using General Zoi's pony Flash tool: ([link]).
I couldn't find a good image of Gilda from the series that I likes, so I created a posable Gilda using a combination of vectors, brushes and Photoshop layers. I used these images to get the look right, Sulyo's Roaring Gilda: ([link]), PeachSpice's Gilda Vector: ([link]), and Elsdrake's Hippogriff Gilda: ([link]). The head in frame 4 was entierly drawn by Sulyo: ([link]), and is used here with their kind permission. As I couldn't draw one nearly good enough. The eye was also Created by General Zoi's pony Flash tool: ([link]) for expediency\consistency.
Fluttershy's Cutie Mark was created by Grendo11: ([link]). As was Twilight Sparkle's Cutie Mark: ([link]).
In case you're wondering, the strange markings on Fluttershy's face in frame 8 is supposed to be a shadow of Gilda as she is overcome by Fluttershy's curse.
The Library scene in frame 9 and frame 10 was created by RilDraw, the original can be found here :
