UPDATE: After responding to Bad-man's advice I screwed around with the panning, EQing and mastering and got it sounding a lot better! I also fixed up the whispers. Here it is, and Thanks Bad-Man!

So, for my album I've tried out a different arrangement of guitars. Rather than a 3 guitar arrangement like my last version, I wanted to push for more rythm and try out a 5 guitar arrangement instead. So far, it doesn't seem to be working. My issues lie within the mastering. Although all of the recordings have a decent volume flow, I can't seem to get the lead and the rythm to mesh well together. At times the rythm drowns out the lead, and if I try to raise the lead, it starts to drown out the rythm. It also doesn't help that my speakers and my headphones aren't showing the same results. This is my fourth attempt at mastering this and it doesn't sound too much better than the first.
Anything that can help is accepted, and if nothing's helping I'll just go back to the 3 guitar arrangement.
