H'okay, firstly, welcome to the forums!
Secondly, this was good! I REALLY liked your use of counterpoint, it was very well crafted and I rarely comment on counterpoint anywhere in the pony musicverse!

Maybe for improvements, make it more dynamic. It was largely the same dynamic throughout and classical sounding stuff is very big on the dynamics! Also, those glissandos sounded unnatural, but I guess that's something that can't be helped...
If you extend it, add some more variation too!
Great to have someone such as yourself here!
TubeyouYou are the hero My Little Remix deserves, not the one it needs.
So we’ll hunt you. Because you can take it. Because you’re not our hero.
You’re a silent guardian of music, a watchful protector of songs.
A doctor of dissonance.
