I like it!
So you have good speakers!!
Well, it's decent. But the percussion is too loud at the beginning, and parts of it tend to be repetitive.
Ok - that's the thing with GarageBand - everything is either too loud or too quiet.
I too get clipping errors throughout the song. Turn down the master track when you share your music... But you should ask your teacher to work on mastering... Also the bass drop was kind of uncalled for.
Too loud. Clips horribly on my speakers.
