You have to be patient when wanting to receive reviews. Keep on writing so that people know that you're motivated to get better. If you just write one chapter and just let it sit, people most likely are going think you're the type of writer who floods the board with unfinished fics.
EDIT: Dude! You have like two reviews! You oughta be happy as hell!
EDIT AGAIN: And don't expect reviews on your first day releasing your fic, dude.
