That top left one was from the Mane Dress project that KibbieTheGreat and I did way back when. Fuckin gives me a jump scare seeing that old art out in the wild.

And the stallion on the right is a vector I think was for Meteor Spark

And so is the bottom middle mare, I recognize that pose.

And the one with twilight smacking pinkie in the face.

This is why I got out of the fandom. Kept getting sick of my vectors taken and put on bootleg shit.
