I Asked Jesus to Take the Wheel...

I am aware that I've been overusing Fausticorn lately, but god dammit nobody's related to anyone on this show. Sure Pinkie, Rarity, Twilight, and maybe even Applejack have parents, but they're not even remotely popular. I bet half the MLP fanbase can't even name any of them; I sure don't. Star Sparkle, Granny Smith... I give up.
Even then the Royal Sisters and minor characters that have a massive following like Vinyl Scratch aren't frickin' related to anyone. Octavia and Vinyl Scratch appeared in different episodes; I'm not surprised that the fandom pieced them together.
I'm only halfway done. You'd think putting in one baby on their own make seem ideal, but for some reason it isn't That's why "How Do I Goggles" got mediocre results. You need a larger pony in the mix to make them look more desirable and cute; more-so an alicorn. So really the only reason I use Faust is because her hair isn't a giant gradient (which is morbid for MS Paint users) and her transparent tinted hair (which is do-able in MS Paint... but still a pain in the ass). Furthermore there's enough pictures of Luna and Tia on the interwebs, why not throw in Fausticorn?
Option B is to use something that's small in the focal point and use that to scale the size of the babies. I screwed that up when making "I Just D'awwed in Your Arms Tonight" with the background; Armor and Cadence should be a little smaller than that. Whatever, abacus, I'm out of here.
