Just wondering, though, is it OK to create works based on this? The CC license you chose says "No Derivatives", which as far as I understand means that while it's permissible to reproduce the image as-is, you cannot modify it in any way. ("No Derivative Works — You may not alter, transform, or build upon this work".)
I was looking to incorporate Fiddlesticks into a background pony project that I'm working on (Daring Do's mane is like Rainbow Dash's only in 50 shades of Gray. GRAAAAY.)
Did you use an "official" color chart for Fiddlesticks? You wouldn't happen to know what color her eyes are supposed to be? I've seen them purple like Octavia's and also light blue, but she didn't open them in Luna Eclipsed or Family Appreciation Day, IIRC.
Update on her eye color... A couple of days ago, I happened to be watching Luna Eclipsed on YouTube to get a good screen shot of Luna's Guards, and noticed that Fiddlesticks does actually open her eyes when the Princess arrives. The problem is, in one frame they're blue, and then the next they're purple like Octavia's, and you only see them for a couple of seconds.
