Wow.
That was one epic song. I like the melody, it was just so cool. The progression is great, too bad you kind of ended at the breakdown. I would really like to hear the whole song!
The song does have a couple of problems. The sweep is way too loud, it distracts the listener, and even kind of hurts my ears a bit. The song isn't quite bouncy enough, you really should try to make the kick a bit harder, and maybe sidechain the pads.
Well... I do hope you finish this, but looking at your profile, it seems like you have a lot of WIPs in there.
