Guitar should come in sooner, imho.  You could use a bass to fill the song out and it would be big.  Personally, for my taste the build is too long.  Remember, I don't listen to this genre unless I am up here so this is just gut stuff I am saying.  About 45 sec would be the latest I would wait.  You can use all your other stuff then behind that.  Just a thought, Biodude.  I am sure you have it the way it fits that genre but, what the heck.  Guitar is a good instrument in there.  As I said, I would have a heavy bottom on the bass.

Nice!   Mix tweaks aside, for me it sounds like the guitar completely belongs. 
 

Thank you all for the comments Mesh and I have taken on board the feedback and we will put it back in the oven and bake the mix a bit longer. It's the first time that I've included live guitars and still finding my feet on mix placement in this regard.
Rejigging the desk area over the next few days and will post an updated mix as soon as it's ready.

Fun - congrats on the collaboration! I'd bring the guitar in earlier, it might hasten the build up, which I also thought might be a bit over long. I look forward to the next iteration.
