Song is "Loyalty" by AcousticBrony and MandoPony. http://youtu.be/voj9MhBUaTI
I know everything I didn't bother to fix, and I'm not proud of it, yet here we all are. Ta-da! But if critiquing makes you happy, I won't begrudge you it.

If you want to see where this is going, read the fanfiction. http://www.fimfiction.net/story/33746/LOYALTY

Originally only an animation, I started writing LOYALTY as a comedy story to help figure out how to fill the space between the beginning and minute 6 of the song, which I never reached. I didn't get to draw a single thing I really wanted to (Soarin's Thunderwings; RD's Buccaneer Blaze, which is worth seeing- I will probably animate it later; the very last chapter of LOYALTY).

I almost made it to where Thunderwings is in the song. Almost.

Q: Where's the rest of the song?
A: I'm not sure I'm going to get there.

Q: Why is RD's Wonderbolt uniform a winged bolt?
A: It was originally a mistake, but when I went to fix it, Dash insisted she wanted a *winged* bolt. Much cooler.
