Hi,
She has a really nice voice. There's a little bit of a country vibe in there.
Do you intend to stick with
straight forward guitar and voice? Personally I would, but I'm just asking to be clear.
The main thing I notice is the ambience on
the acoustic guitar. It's probably just the sound of your room and, I guess, it's less noticeable on the vocals because the mic would have been closer for vocal recording.
Perhaps you just used one mic for this whole recording?
There are a few things you can do, if you want a drier, closer sounding acoustic guitar.
If you're just using one mic, try two - That'd be the first thing.
If not, take a look at mic position. How far away was the mic? Is there room to move in a bit?
Room treatment helps a lot.
You don't
need to go nuts and pre your room like Abbey Road. Even some heavy blankets hung up can make a decent enough difference.
Tell us more about your setup.
PS: No one's going to cringe over any of the above. If you just want to showcase her voice I think you've done a good job.
