Help with a song

[Reality_is_a_Dream]

I hope this is in the right place, feel free to move. I made it with Reason 4. This is the intro and verse, I'm going to do a pre-chorus and then a chorus and go from there. My female freind is going to sing the piano part, but with lyrics. The tempo is 97 bpm, it's in 5/4 and A minor (but I am going to another key for the prechorus, I am thinking either Em or Dm). The problem is it sounds a little hollow, and I need someone to critique it. Please help me, DV. Thanks in advanced. http://www.youtube.com/watch?v=LjMdR_kqnHU I know youtube quality sucks, please recomend a good hosting site.
