Yeah - I like this. Of course, I've heard Janet's piano work many times and is always solid.
From a production and mix standpoint maybe hearing the instruments defined more from "front to back" rather than from "side to side"? Strings in the far back; piano "phased in" to sit up close but from behind the listener (some M/S channel tweaks) so it is not competing in the same frontal direction as the guitar.
Like some others have said, there might be some movements in here that clash, but it's sometimes surprising when getting the mix tweaked with some depth tactics how some of that can disappear.
But don't let my production comments above take anything away from the solid musical talents you both display. This is very nicely performed.
