I recently started making resprites, and in that, I've been able to come up with acceptable ideas for the Celestial Pillars from Terraria!

The general idea was to make them "actual pillars" and have it be a representative of their race embedded in them. I meant to resprite the rest of them but y'know, kinda not the best at doing things at the same time, haha. A lot of inspiration was dragged from the odd little statues you could find on Pyramid Ships in Destiny 2, as well as some other interesting ideas (see the Man In The Wall from Warframe)
