Sweetie's cutie mark is explained in my fanfic, 'Scion of Chaos', and the meaning behind Scootaloo's cutie mark is something that Scootaloo is still struggling to understand on her own in 'A Heart of Change'. If you feel like reading an children's adventure, you might want to give 'Scion of Chaos' a read. Many of my readers have quite enjoyed the story. But I can also understand if you wouldn't want to read a novel. It should suffice to say that there are sound reasons and context for the cutie marks to be the way they are.
I do have to agree that it's a lovely picture. I'm quite grateful that Tails was willing to commission this for my story as a birthday/Christmas present. It was a very flattering gesture.
I just love this fic so much, just finished reading up to the current chapter and am so eager to keep reading, I was especially stunned to discover that it had a chapter for The Sweetie Chronicles: Fragments, which I'd forgotten to monitor lately and had to spend time catching up on before I could continue A Heart of Change.
It's those enormous and amazing collaborations that remind me of just how awesome the MLP community is
Scootaloo's mark is a purple triangle with purple wings. She thought that it was supposed to represent her ability to fly, but at this point in the story she's has to wonder what it really represents. She's no longer as certain as she once was. Of course, if she's not certain on what the mark means to her, then who knows what it really represents? I know why I chose for it to be that way, and what it represents to me as the author, but I'm not about to give those reasons away since they will be explored further in the actual story.
I know that's not exactly a very eye-opening answer...
Well, there's certainly a back-story to it, explained in the story 'Scion of Chaos'. Many people seem to think that it was worth the read. The mark does have a great deal of meaning to Sweetie as a character in the story, though it doesn't have any direct link with Cadence.
*faves it imediatly* ZeroZi said it best when he said this was outstanding work. I love it, paticularly the ribbons in Applebloom's mane and tail. She's sooo cuuute! I've been looking for someone to do cover art for one of my fics, if your interested, please send me a note. I would LOVE to have someone of your tallents making a cover for one of my fanfics. If not, I undstand. You proabbly have comissions and requests up the wazoo.
