Truth!
Reverb much though? ;)
And lots of low mid bloom and resonance...your room I believe, mainly. Possibly placement of the mic as well. Likely both. The line connecting 'thin', 'balanced' and 'bloaty' can be a very short one, especially when dealing with an actual physical space, with walls and stuff. Try keeping them under control with a multiband compressor when in the mix, and/or micing aiming more at the neck than the body. Pointed at 12th fret can be good if positions aimed at the body are proving boomy. Stay away from micing at the sound hole. Very bad. Also, if you can move around in the room or have someone hit 'record' and 'stop' for you then where in the room you place the source has a huge effect.
But, nit picking, if this be an early effort, its well done :) (I know the last thing that someone thats rightly happy with what they just did wants to hear is 'constructive criticism' but there it is; for your consideration :); it does sound nice, I just cant help it!)
Nice piece piece, well played too.
