Now the acoustic doesn't sit well with the vocal. It sounds a little flabby and probably could be re-tracked. I think maybe you could have kept the top end but slowed the compressor release down so that it wasn't so jumpy.. the biggest thing bother me was how much the acoustic was jumping out so much. It's close though...
Regarding the -2db on the master... holy sh!t what a difference!
I pulled both mixes into Cubase and just droped the old mix by -2db. The new mix kills it... you can actually hear kick and snare... the whole mix has balls now.
Anyways... good work dude!
