I will give you credit for your work ethic, you've obviously spent a lot of time on this track.
But except for the clipping, which it has to a major degree, it's a solid brick. By the time I get through almost 4 minutes of solid sound at -8.8dBRMS, my ears are so fatigued that the Justin Timberlake Autotune is probably the least annoying thing I hear.
Back off on the dynamics pancaking. All it will do is get people to take that song off of their playlist rotation faster due to sheer fatigue. And throw in at least one instrument that doesn't sound like it's coming off of an 80's synth drum pad. I understand that's "the sound", but all light and no shadow is almost never a good thing; you need *something* to counterpoint or balance the sound.
You've done a very good job, actually. Unfortunately you've done a very good job of mimicking the worst habits of modern professional music production trends. Take a complete vacation from music for a month or so. No radio, no MP3s, nothing. Read a book. Then, once your ears have become acclimated to real life once again, come back and give that mix a listen and decide for yourself if you really think it sounds as good as you do now.
