Once you've sorted out your typography then I think that the flyer will work aesthetically. It's what i'd expect a club flyer to look like so you've clearly done some research on that part.
Also, i think that you need to have a look at the content on the flyer. Why would people come to your club night? Try using an incentive and make that the prominent feature to entice your audience (i.e. Free drink upon entry).
Additionally, i'm looking for contact information and there is nothing there. Website, phone number, email address. Possibly look at making the flyer double sided and adding a map (you'd be surprised at the differences that these little things make).
