Really nice! I liked the sweeping pads a lot and the occasional bells reminded me of a hat in time!
I'm not sure this fits challenge C however. Challenge C would mean that if I played this song in reverse it would sound exactly the same but I don't think the drums or the bells would work the same reversed. I know challenge C is mistakenly displaying challenge A right now but I wanted to point it out.
And don't worry I'm not docking points or anything since there is still very clearly palindromic elements.
The track is very good and I thought the percussion was very well done as well with how complex it felt!
