Sounds a bit compressed,
Not sure if it is compression individual tracks just the master bus !
I used an SSL Master Bus compressor with only 2db of compression.
But I did compress likewise on each of my buss masters, using different compressors and I did have a lot of bussing going on.
I'm still not 100% with the mix so I'll try backing off on each of the busses a bit and see id that helps.
Thanks so much for your comment.

The balance is good .
If you haven't tried this, I had a lot of trouble with a build up of low frequencies especially on electric guitar 1 and drum ambience track 1 and removed all frequencies below 200hz to get the music breath ,but usually tend to over do it LoL.
