Hyde formula?

“Andy Price notes in his interview that the artwork for Reflections went through many revisions, because Hasbro was making many changes to the script even as the art was being drawn.”
 
…Well, that would also explain some of the problems with the story if the script was being changed even as the art was being drawn (the usual idea is to have the script finished, save for possible minor edits, and THEN start on the drawing).

star swirl and celestia,  
nice shipping

Holy crap, what a nightmare. Did he have to re-ink any of them?

@soundtea
 
It does sorta explain their lack of progression though.

@PonyPon  
Yeah, to be honest I wasn’t exactly fond of the implication that Equestria’s advancements were stolen Bioshock Infinite style.

HMMMMMM  
 
The flamingo (I’m guessin) in front has the rough pencil of Cele’s CM.
 
That would make the back one being Star Swirl, giving his CM being that similar to the Vulcan writing that Price has used before for the comics.

@Background Pony #1936
 
That’s a crying shame.
 
I would’ve liked some starswirl the goatee’d as well.

It’s interesting that the Otter part would lead to explain the EQG-version of the mirror, allowing species shifts.

Another thing I noticed: in the initial sketch stage, Star Swirl looks younger in the first panel than he does in the last, like he and Celestia have been doing this for years. In the final version, he’s the same design and age throughout, implying the events took place over a much smaller space of time.
 
This is weird because the final version has text reading “And so it continued for decades.” Therein lies a problem: why isn’t Star Swirl aging? Celestia is understandable, but Star Swirl isn’t a god or anything. The text fits better with the sketch’s narrative than the final version.

Oh yeah.
 
That other thing I wasn’t fond of in this comic.

Notice Celestia’s horn length?
 
Andy Price originally drew Celestia “younger”, with a build similar to Cadance. Hasbro had him change it because they decided Celestia should look the same 1000 years ago (as seen in the Princess Twilight Sparkle flashback).
 
The magic mirror also changed appearance: it used to be the same as the one from Equestria Girls, but Hasbro decided it should be a second mirror instead. My theory is that this change was because Hasbro wanted to keep the orignal mirror intact so they could have a way to continue Equestria Girls if they wanted to (which they did).

Looking at both of these, I still have to wonder if it was a responsible use of magical powers.
 
It sure looks like some fun adventures. And if a lot of pony technology was borrowed from other places and times, who could fault them for improving the world?

Both Disco Celestia and Otter Celestia need to be a thing.
