Terrific blues, Dave. Your guitar is on fire.

I think Chris' vocal needs some clarity added - just a bit - it gets a little lost in the mix in the beginning. It might just need a small bump in volume (1 dB maybe) or an EQ bump in the upper mids (that is just a guess... maybe around 1K? and again, just a slight bump - nothing dramatic). A subtle lift.

Everything else sounds great.
