one good tool for checking the loudness of your masters, at least you are not as loud as Metallica's Death Magnetic
I did notice from this that phase correlation meter was not in positive very much and pushing into the negative a fair way
this indicates your L&R sides are out of phase, sounds wide in stereo but causes many problems on badly set up playback systems and a general loss of power on many playback systems.
it sounds like the cymbals and the guitars are out and this was confirmed by their huge reduction when I hit the mono button. I did this with the mix not the masters but the mastered versions sound even more phasey as the guitars get pushed louder with this much master compression.
