Link worked... Not bad Capt!
I think the "narrowness" is coming from layering on top of the completed mix for the backing track, there's not much you could do with that as is. I'm not sure how many guitar layers you have in there, but if you have multiple you could pan them heavier. You do have a cool stereo chorus in some places that sounds nice. Also, some mid EQ cuts to the backing track may make a little more room for your tone, but may start to kill bass / drums if you go too far.
