Well..
Sounds like some poorly sequenced and drums that do not fit with their respective samples at all. I assumed you just used all the white keys on a piano roll for your melodies, considering it's in the key of C, and the melody isn't diverse at all. The tempo changes sound very weak, and not energetic. Again that's when you're using the wrong drum samples.
Also, what's a melody without a chord progression? You have two instruments here, a rather annoying synth and bad drums. The silence before the crash cymbal sounds very out of place, and I basically agree with the last reviewer. You need more experience.
