I'm at work right now so I'm working from memory here, but I did downlod your tracks and worked with them a bit.
I'm not a professional audio engineer, but if I were mixing this for a fee I would request that you re-record the tracks.............and here's why!
There's a LOT of background noise in these tracks so the majority of what I was trying to do when I fooled with them is repair work, which shouldn't be necessary. Especially with such a sparse mix, every little noise will stick out like a sore thumb.
There's a lot of hum on the vocal track and fairly loud hum at that. Removing it in the mix is difficult to do without affecting the general quality of the vocals which aren't badly sung at all.
The very first lyrics on the track are distorted because your plosives are so loud. So turn it down a bit, and pull your head back from the mic some.
From a musical standpoint, you don't have any bass or any percussion so your rhythm has to come from somewhere else. In this case it would probably be the acoustic chords you've got going. I can tell you played them to a click track because they keep a constant rhythm, but they jump around in some places. So I would re-record those and try to get them as as rock solid as you can, no effects, just good rhythmic chords. Also if you double track them (record them twice and try to get them to line up as closely as you can possibly manage) that will give some options for stereo mixing. The finger picked guitar is your expressive part. It's not too bad here, but I think again you could turn the gain down a bit and work really hard to get it to click in time with those chords.
And the backup vocals don't need the effects on them. Just record them clean and leave the options for effects for the mixing.
Lastly, the pads (strings) sound okay, but they repeat over and over and over. If you can change them up slightly here and there it will give the appearance of movement throughout the song. A repetetive pattern like that will eventually become boring to listen to, so chordal changes and melodic movement with those will give that track a little more character.
Now I know that was a whole crap-ton of criticism but I HOPE that you'll see it's just constructive. The song is good, your voice works and the guitar is good enough, but I have no doubt that if you set your mind to it you could record them a little more clean and more in time,
most of the problems here are recording issues, not mixing ones. Spend some time to fix some of the issues the people here have mentioned and repost with new tracks and we can surely squeeze a better mix out of it!
I sincerely hope that helps.
...and still getting acquainted to my monitors.
