And there is a lot of mid-tone sound in it, so I'd turn the mid-tones down a bit in eqing each track or input and maybe on the master too. I always add a little reverb to everything too. Just enough to where you can barely hear it if you are listening but not enough to wear it's obvious. That little reverb gives things a little more meat and makes them sound more full and less flat.
