Are the guitars taking up all the space?

yes, the guitars are taking up waaaay too much. I can't tell if there is bass or anything on the song. Deffinately get the low end under control on the guitar!
 
I'd say it's the low end mud that is taking all the space, but the problem is more on the balance and quality of the recording of things also. For example you should be able to make the basic mix balance sound decent with just adjusting the faders. quickfix to clear up the low end is to just highpass everything else except bass and kick from 100hz and also remove some low mids from the guitars.
