Didn't really prove any point..
Not trying to be negative or anything, but this doesn't sound anything like a deadmau5 song, I can't even call this a quality progressive house song. I'm getting a bit sick of people saying all of his songs sound like this. ONE song sounds like this, except it's a lot more developed, and that song is Faxing Berlin.
You could get away with a song sounding a bit like deadmau5 by using sidechain compression, which he does use A LOT. It sounds like you've used it a bit here, it sounds great with a patch called "Chords of Life" on the z3ta+ VST.
I just noticed you don't have any more submissions, so sorry if this felt like an attack on your skills, I'm just saying, this isn't his style.
I try to stay away from copying others, especially deadmau5 because he's one of my favourite artists. Keep experimenting with your own little styles and techniques. Once again, don't take this the wrong way.
