I like the big drum and the static sound that you start with and use throughout. I think your mallet ostinato has a good sound to it - at the same time I would have liked to possibly hear some motion and some sort of chord change. I do really like the downward pitch bend and think that was a really cool effect. The sudden silence was a little confusing and I wonder if filling that space with some ambient sound or some reverb would help fill that gap a bit. Overall I think you did a good job, and thank you for sharing!
