Great job so far! I think everything sounds good, and the levels are pretty much right on. If this was my band, I'd ask you to turn the guitars down 1db and the vocals up 1 db. Seems like the guitars are masking the vocals too much for my taste.
It almost sounds like the guitars are distorting (not in the intended way) a bit. Are they compressed/limited or do they have any tape saturation or any post distortion? It could just be that they were tracked with more gain than I prefer. Seems like the "less gain, more mids" rule of tracking would apply. Perhaps any double tracks could be dropped a touch to make the guitars sound a little cleaner. But again, I'm knit picking, it's really a great mix.
