I quite like the percussion, I've never thought of trying half of what you have going on here. I love how you used tempo changes, but the key changes were slightly unexpected. Also, some of the notes felt off. (I could be wrong, but somethings in there struck me as being "weird"/dissonant.) A notable example would be at 3:53, the longer/held note there seems off to me.
Overall the track is reasonably well made, mixed, and mastered. It wasn't the most memorable, nor did it specifically appeal to me, but it's a decent track none-the-less.
