Good use of percussion. Great use actually, it's constant change throughout the beginning kept my interest. Sadly it didn't change much after. The synth underlying in 1:04 fades under the mix too hard. I suggest adjusting the phaser. The ambience effects were nice, but only keep attention for so long. Needs a break earlier imho but the break around 3:33 was done well. And the sub bass is a bit loud.
