Sounds good for the instruments used
You've made good use of the instruments you used, and it sounded good, but there was a definite lack of transitions. The seem to just go from one part to another without the slightest warning. For example, the change from the breakdown to the chorus at 2:02, and even at the begining at 0:13. Sometimes that's good for a dramatic feel, but it doesn't sound right without any transitions. I would suggest a snare build up before the change in melody for starters. I love the breakdown towards the end, I would just add a little more to it to keep it interesting, like maybe a sudden stop for a sec, and a short dramatic reentrance, or make the percussion a little crazy for a couple of seconds.
