If you can play that tight, why not quadriple the guitar tracks? That would give it more gain automatically... very tight btw, nice!
I can judge it better with bass though, it's hard to be critical on what is initially a dry mix with missing elements.. that being said, it sounds cool so far.
Oh yeah, transitions should have cymbals dude.. i cant stress this enough! some people forget cymbals on crucial moments of a song.. it needs it.
