(NOTE: I haven't seen any complaints about "Equestria Girls"'s character designs, but I have the feeling that at least one part of the MLP:FiM fanbase didn't take 'em well. Please, PLEASE do not bitch about them here)
You ever have a pic that you intended to ink, but then you looked at the sketch and decided against it? That's what happened here.
Mostly just wanted to draw EG!Fluttershy and my humanized Fluttershy in the same pic, with Rock in-between them. There was gonna be a "Threesomes are Magic" joke in here, with Rock suitably angered/flustered, buuuuut EG!Shy is clearly underage.
Changed up my Gijinka-Shy's hairstyle slightly, and gave her green jeans.
And BTW what's MLP:FiM?
"MLP:FiM" is shorthand for "My Little Pony: Friendship is Magic", a cartoon that IIRC began in 2011.
