Good tight guitar playing.
For my tastes I thought you had the gain set a little bit too high. It makes them a bit too fuzzy and indistinct. Personal taste thing, but I'd also back off the reverb on them. The verb might not be as noticeable once vocals are in. But it was just a little too wet for me. I'd also start the doubled guitars earlier in the song - don't make the listener wait for the full force of them.
Turn up the lead guitar licks by probably 5-6 dbs.
I'm sure you'll get some comments on the drums.
Oh and the overall level of the mix is pretty quiet.
