OK, but Golden Feather” tag must be here.

Hello, fellow users of this website, on which I registered specifically to write this comment😎 I’m the author of this series of drawings. And yes, these are some illustrations for the “Sunny Skies all day long” fanfiction.  
We used Celestia’s diquise from the comics for the sake of reference, because we are translating and dubbing not only fanfics, but comics as well. From a technical point of view, Celestia’s disquise didn’t even have a name in that comic, it was given her by fans, so we thought that naming her Sunny Skies is fun.  
I beg you not to put spoilers on these pictures and not to remove Sunny Skies tags. At least you can leave them along with the Golden Feather tag. Ty!

Well, that’s nice and all, but that’s still Golden Feather.

different people could come up with different Sunny Skies. they just have the same name, but they are completely different mares

@Tantabus_horny_pony  
Except that totally Golden Feather, Celestia’s disguise from the IDW comics.  

 
I have no idea why the artist changed their appearance, but this is what Sunny Skies was supposed to look like in that story.

these arts have nothing to do with comics, these are illustrations for dubbing fanfiction. so yeah it’s an oc

It’s Golden Feather, not an OC.
