The last one I was commissioned to do was the fashion designer of the town, Rarity. I had to make her look the most mature of them all. I was going for a cheesecake look of her trying on different bras while using her magic to try them all. This is like the polar opposite of the Fluttershy pony. I assumed she is more aggressive and least shy of them all. I feel she is the most Vein being that she is the stylish of them all? Knows the latest fashions?
this one took a while to go cause I was going for the mirror effect like I did with the Mrs Bull pic I did a while ago.
To answer your questions on Squeek and Shred?.....Squeek would hang out with Fluttershy while Shred would totally hang with Rarity and Applecack.
