Edit: 6th panel, pony to the right. It's Apple Cobbler. Not Applejack. The missing hat, the missing lines in the mane, the multicoloured tail, the different colours, the different hairstyle and the different Cutie Mark should be a hint. Just to clarify.
Hey look, I made a comic. In colour. And with backgrounds. For My Little Pony!
Yeah, I wanted to draw a comic for some time now and yesterday, I had the idea to this. I've realised that the more I draw the princesses, the more I like them. I just love drawing peaceful moments between them.
I'm terribly hungry right now because I was working nonstop in this the whole day without eating. Enjoy while I'm going to cook something.
Edit: Fixed a few things, thanks again to the people who've pointed out mistakes :3 This piece is now the most faved, commented and viewed of my gallery. Apparently, people love the royal sisters and d'aww-moments with them.
Since Luna used to have a regular violet mane before her magical one, some people in the fandom (including me) concluded that Celestia probably used to have a normal non-magical mane too at some point. The pink colour comes from the very first minutes of the very first episode, where Celestia is portrayed with a pink mane in the story-book.
