Awesome song!
It's a bit sad for me, but it's great.
-The guitar is a bit conspicuous. The strumming noise is too loud, and it repeatedly keeps tapping. It's kind of annoying (NO offense intended), so pipe it down a bit. That way we can concentrate more on the actual guitaring and singing.
-It's a great song, but the guitar needs more variety. It plays the same progression through the whole song. Switch it up by playing fifths, sixths, sevenths, or any other chord that sounds good and matches the singing.
-It's just too great a song. Make more lyrics and make it longer, PLEASE.
Other than that, this song's about good. You could become famous. Make other songs and you could be better than some of the greatest rock bands out there ;)
