First of all, good to see a fellow Aussie musician!

I love the ambience that the introduction of the song brings. Great work layering those instruments when the drums come in, excellent to see you using different instruments to add some different colours into the song. The only thing I would say, it goes on a little too long. Of course, I have no idea what your going for, and vocals would definately change this.

Good work, I really enjoyed this. Also, I think you would get some more views if you added the fact you have GP files. I guess people are off put by the fact you only stated MIDI?

Take it easy and keep it up.
