I prefer Flutters as an Earth Pony and Pinkie as a pegasus because I think that Earth Ponies would be able to tune in and listen to "The language of the earth" and were more down-to-earth(no pun intended), and usually had cutie marks that had to do with biology, gardening, or catering, while pegasi were more lighthearted and thought everything was always going to be ok, forever, and had the more diverse talents that they could probably do without their wings, like hoofball(football/kickball) or matchmaking. (Unicorns would usually have more refined talents with a bit of diversity, like art, song, and business)
OMG, she looks like Rarity! I don't know why I loved it slightly more than normal Fluttershy/Rarity. If someday I try to do a G5 (I'm a straight boy but I would love to do that), I'll make a pony who looks like both Rarity and Fluttershy.
