Sounds nice. Here's what I'm hearing:
Nothing wrong with the mic's or pre's IMHO. All nice stuff.
I would try something different for mixing. What you have sounds pretty good but I think the Piano is just a bit loud and it sounds like you might have gone after some low end on the bass to get it out there.
Hey, it's gona bleed. So, start the mix with the bass. Get it cookin' nice so we can hear his hand on the finger board. Make it a little brighter {as in, start with no EQ.}
I'm saying I would mix around the bass. get it sounding great. The drums will spill all over it. Fine, make the bleed work. After you dig the bass, get the piano up and going and last,bring the drums up. You will need a little less drums because of the bleed from the bass.
I know it can be a pain in the ass but try to make bleed work in your favor.
My 2 cents.
