The quality if pretty good, but the song could use some filling out, with a fuller acoustic sound, or maybe some bass guitar. Also, it's be cool to hear a cello or some lower end strings going on, maybe even bass cello.
Also, I think a song driven so much by melody like this could use harmonies.
I don't know if someone has said this before, but this reminds me so much of Goo Goo Dolls, especially the first song posted in the thread.
You have serious potential, man. Good work.
