Sorry for the longer wait between pages. This past week was a bit rough on me.
Anyways, I feel like this page may require some explanation, more so than the others for sure. I always imagined that Celestia would have to feel incredible pressure to BE perfect to always make the right decisions for the sake of "harmony" for the "people" and so forth. Even if those decisions would eat away at her on the inside emotionally. this is basically her reaching the breaking point when something good happens to her she feels unworthy of it due to all the bad things she feels like she has perpetrated for the sake of harmony and stability.
I dunno, this is all just headcanon fluff in the end, so feel free to diagree, but this is just my view on things.
I like to keep powerful figures emotionally vulnarable.
