Guitars are a little loud. Drummer is loud too, but hey, what are you gonna do play with dowels? It'll sound lame. I think you could use a little more volume and the guitarists could use a little less. Again, this is a live recording. A lot of video cameras that have been used at my gigs that aren't professional, will really catch those higher frequencies and the bass will be totally lost. I've had perfect mixes before, and all you hear on the recording is guitar and snare.
What you might want to consider, is putting more guitar in the monitors. That way, your guitarists can hear themselves perfectly, but wont have to BLAST their amps. Also, move your amp closer to the front. If I'm in a situation, although rare, where I might have this problem with no PA support, I'll place my cab directly in line with the front of the drums instead of tucked back behind it. Just because your drummer and my drummer both have loud sets!
Once your guitarists have a good monitor mix, your amp is either in the PA, louder, or moved up, you should be fine. But again, it could have sounded perfect there. That's another problem with the live recordings. Your singer sounds like she's semi straining to hear herself, or project louder. Could she use more monitor as well? I think she could be brought up in the mix a bit as well. Just based on this vid. Good luck! Hope we can all help you out.
