This is awesome, haha. XD
I love the concept & your art is very pretty too. :)

fwahhh this is soawesome. i LOVE the way rarity looks

ahaha absolutely love this! ^^

So, Applejack stayed with the Oranges, becoming a haughty cocktail-circuit pony, while Rarity put her meticulous attention to detail and telekinetic dexterity to good use in mechanics? Lovely!

Hmm, given the whole affinity with diamonds in the normal continuity, I'd have expected her to be a miner, actually

Still, awesome :)

That's an imagination tickler of a concept! Great renditions of their possible alternate selves, too. :)
After all, AJ's worker's mindset could as well have been used for social networking /rank-rising and keeping track of trends and "important" people, and Rarity's creativity and knack for details would have been good skills in engineering, too. (Hey, there's industrial-use diamonds as well)

They became friends in spite being as different as night and day anyway before.
