Nice, festive offering!
Like your red jacket. Buy a set for the band… Kind of that Paul Reverie and the Raiders look.
All sounds pretty good. But I am thinking one could tinker with the drums a bit. They to me are a bit high, almost on the tinny side. One can add some duct tape on the underside of the heads and strap on a rag or something to kind of deaden them a bit and produce more of a thump. You could also add a pillow perhaps up against the kick to do the same sort of thing. An example of this is on a song we came up with way back as our 2nd offering. You can check out the start and then skip ahead to 1:01, where there is a drum run. That will allow you to hear what I mean.
On the vox difference. @DavidP I think is saying to simply pull Jen up with EQ and drop the other singer down via EQ. At least experiment with that and see how it pans out.
Cheers for the New Years!
