I wouldn't worry too much about the panning even though the gentleman below has a good point.
The problem with the panning as it is now is the song's lack of centered melody or a carrier tune to balance the difference between the sound reception. Imagine it like this. Ever notice how some people find 3-D movies uncomfortable to watch? That is because of a rapid flicker between the rendered stereoscopic imagery and an impartially flat one. This can be applied to hearing too. The brain is constantly struggling to merge the two sound inputs without a centered ground. This doesn't happen all that much in real life because of the sound not being stationed right at your ears. People who listen in speakers will probably not have the same problem.
That aside I find as the song is a bit rough. It is, in my opinion, allright to keep it that way, but when everything comes as an unfiltered saw, it becomes a bit irritating.
But I'm giving you a nine because this has a nice structure and the mix is otherwise really really, really good.
