"Amplitube" sounds pretty cool to me.
"Chris's Acoustic Song" sounds kind of harsh and brittle. A little to "roomy" for my taste. Recorded with one mic? The guitar sounds out of tune. On second thought, intonation is not your strong suit, evidently. Is that a phone I hear ringing? Funny.
I think with a bit more attention to the basics (playing/singing in tune, for instance) your recordings could improve tremendously, if this is any indication.
