I thought the performance was just great, so I won't comment further about that. I doubt you could improve it.
As to sonics, they were good. Some things that may improve them though:
1) I would back off the reverb a little for both the instrument and vocals.
2) I may be wrong because we're trying to cut down on our electric bill, so I've got a fan going a few feet behind me instead of having the air on, and it may be mucking with the sound a little, but it sounds to me like you might have a bit too much compression on the guitar. (Now I'll really feel silly if you tell me you aren't using any at all!)
3) I think you would benefit from having the mic closer to thicken up both the guitar and the vocals.
4) I used to have a 314ce with the 1st Expression System and found a Boss AD-5 preamp thickened it up considerably. I don't know for sure that it would work on the newer one, but it might be worth looking for a used one. Boss never should have quit making that unit.
Again, your recording was very good and the performance was perfect. I'm just suggesting things that might make the recording even better. And I could certainly be wrong!
