Alternating between your mix and my slight alterations. Of course, the difference isn't as high quality as it would've been if this hadn't been mastered yet, because of headroom and such. But You definitely get the point.
Your mix sounds REALLY good, but there's just some stuff that sticks out. The uneven high and low end, and the aggressive 4k to 8k areas hurt the mix a little bit when it comes to translating across different systems. REALLY good overall though. It could just fill out a little bit, and it will sound much better if you do it than me doing it to your mix! :)
