Rarity would be the first to fall. She gives too much of herself.  
Applejack would come second. Her life has been ended, and her entire unlife is a lie.  
Then Pinkie Pie. Smiles and laughter would die away after such tragedy.  
Twilight Sparkle would be the next. Her friendships would dissolve under this unholy pressure, and the very magic she loves is destroying her.  
Rainbow Dash would be broken, resisting to the very end. Too loyal to her last remaining friend to let herself stop, but without the strength to save herself or Fluttershy.
 
Fluttershy would be the last. She is stronger than ponies think she is. And she will either a terrible witch, or become the kindness of the next world.

Also, I’ve just seen the wing-like decoration on Fluttershy’s back. Nice touch!

Just like your other image (I was the one who blabbed on about Pinkie’s attire XD) this is original and really nicely drawn. Dashie’s dress looks like Kyoko’s to me, but not so much that I’d call ripoff (besides, they’re both really similar characters anyway). Twilight’s dress is surprisingly detailed and regal, which to me is a good nod toward her alicorn state (or, as I’ll guess in this version, her ‘ULTIMATE GODLIGHT SPARKLE FORM’). Also, I really love her staff!  
Fluttershy’s dress is great too (simple yet elegant, probably the way she’s like it), but I can’t really see her using knives. Still, a point for originality there :-) Overall, one of the best pieces of fanarts I’ve seen. That goes for your other one too.

Dashie looks badass!
