I'm hearing a bit too much limiting. Everything seems turned up to the max. It's fatiguing in wince factor to listen to accordingly - and it has got a midrange nasal quality to the overall mix that is the likely result of the harder limiting byproduct. When all the frequencies are squished, the mids become FAR more prominent. The fix is merely dial back the limiter until it sounds more natural - and "air" returns around the performances - so they become better defined in the space. Minor mix adjustments will be needed, likely, to account for the change in relativities due to less glue.
Levels/Panning etc ... are all in the right ballpark. Vocal is lacking edges - meaning it's not in a "pocket" - but that is (again) likely due to the limiter squashing everything together. There is no pocket to sit in when pressed hard against everything else.
Not really a problem with the underlying mix, per se (given minor adjustments). It's the application on the two bus that needs the most address.
