A good launchpad you have here with lots of opportunity – a decent central character, though a word of advice not to let him go down the sterotypical ‘down-on-his-luck musician type’… Shake things up a bit!
This was a good launch pad, but I want to suggest a few things:
A. When he said his back was killing me, there should be a comma after the last word in the quotation marks.
B. I think it’d be better if he thought what he said, cause he comes off like a creep talking to himself, you know?
Maybe that’s just me, but it’s just a suggestion.
C. “He could see his dream dying before him. All he ever wanted to do was play in a rock n’ roll band.” Could be changed to one sentence.
“He could see his dream dying before him, all he ever wanted to do was play in a rock n’ roll band.” It’d flow better and you do use a lot of unnecessary periods.
You could also reword:
“He had to get a day job working in an apartment complex, doing maintenence. Vince hated it.” So that you don’t have “Vince hated it.” In it’s own sentence. And you spelled maintenance wrong.
