Hey man...pretty cool. I listened to "2 Against The World" and "Break A Man," because those are both great titles. The recordings were very clean, and I'm kind of a minimalist (at least in what I listen to), but I think even some really additional subtle percussion (like the shaker - good idea) will add a lot. I also think that you'd benefit a ton from some vocal harmony. I don't think you necessarily need (or want) the "FULL BAND TREATMENT" for these tunes, unless you do it just right (something I can't seem to do).
Ever notice that when people describe somebody as a "Singer/Songwriter," it's usually because the artist can't sing? Seriously, like John Prine...he'll ALWAYS be called a singer/songwriter, even when he's doing covers. LOL. Like it's an excuse for the voice. Clint Black writes every song he sings, but you rarely hear the moniker "singer/songwriter" associated with him, because he can freakin' SING. I'd put you in the latter category, b/c you've got a very good voice.
I definitely want to hear this when you've added some stuff.
