The bard brings the noise, or otherwise, every music effect I felt like cramming in there, plus a reference to the 1812 Overture by Pyotr Ilyich Tchaikovsky, aka the one with the cannons in it. Her whole thing is music, and I feel this follows a decent enough beat.
And also, because I never posted this here, this is what the outfit is based on. I made this for a school project, so I made it really simple to animate for time reasons, but ended up loving it because it's so cute. It was for a game I made, and I just ended up making it about this character because the challenge was adding cues via sound, so magic music girl seemed appropriate. Plus, look at how bouncy she it!
