woaah repetitive woaah repetitive woaah repetitive
Your main problem is the fact that you're looping the same thing for the *entire* four minutes and a half, with little variation other than a slight change in percussion and an even slighter change in synth.
If you're making a song this long, you need to develop that melody, USE the 4 minutes to expand the song. Otherwise just save the first 30 seconds and post it as a loop. At this point, we gain nothing from listening to the whole thing.
Introduce new instruments, vary the melody, create a counter-melody, use some chords to change where the song is going.. There's a lot to be done.
If you choose to repeat something so much, make sure it's worth repeating.
