I noticed that you have a huge gap of silence at the end. Seeing as this is your first song, I'll assume that you don't know that there is a marker that marks the end of your track. Go all the way to the end of the time line, as far as you can, and you will see a grey marker type thing, you can click on it, and move it further up or down. I didn't know about this at first either. Hope this helps.
awsome man you rule
