Too random
Alright I'm going to try to give you as much feedback as possible, to help you out with the contest.
First off, the whole song sounds really random, there are long pauses between some parts, and some things don't sound like they fit together. Make sure your song sounds like one whole song and not a bunch of clips.
In the beginning, you have a snare hitting on the first beat of the measure, which sound very awkward. In a basic drum beat the snare will hit on the 2 and 4 of a measure in 4/4, not the 1 and 3. It throws off the beat.
Try putting your parts together using a metronome, and only put new sections in at the beginning of each measure, not over another part. This will give a better feel to the whole piece, it would sound like it has hic-ups in places.
Hope you do well, and that other people leave you other comments.
Good start, and keep at it!
