I think one thing that I do like about the "Ascension AU!" series is how the Mane Six's new forms call back to creatures and people (that is ponies and other sapient beings) that help shape who they are in some form of fashion.



This is pretty clear with Rarity having an appreciation of Crystal Empie way back when it first appeared in Season 3. Especially with your Rarity butt-kicking the Crystal Empire's greatest enemy.



I definitely love Rarity's design for showing how otherworldly the Mane Six has become while still retaining the character traits that made who they were pre-ascension.



She also kind of reminds me that one day Equestria will wake up to their heroes becoming about to the similar power levels to the Princesses, and would forever change the course of Equestria and the world.

And I bet they would be met with great enthusiasm and great fear.
