You, unlike most of us here, have a timeline to get these finished as well as possible, so you'll have to make some compromises.
I would say that it sounds pretty good. For a Christmas present for your dad? He'll think it's great (unless he's some sort of music producer) and he'll probably end up showing it to all his friends.
it sounds to me like some guitars are recorded direct, and lead/solo guitars (banjos? resonators?) are mic'd. The mic'd guitars sound much more distant and roomy than the rest of the mix.
It also seems that though your vocals are hanging out a little to the right. Either that or my left ear is starting to fail me.
