Replace all unreadable or hard-to-read typefaces.
Replace or remove graphics that interfere with readability of text.
Find the harmonious balance in the text to graphic ratio.
The first one is good, along with the second; however, the latter contained some hard-to-read typeface due to the choice in font color. The third one also has some hard-to-read text due to font and graphic color combinations. Fourth one looks like you put a business card on top of a car ad (looks like two different ads on one page), but gets the message across none-the-less.
About FB page.
You should put the Facebook page to good use by posting additional details about "WHITE PARTY" "Karaoke Night" "BLU __________" and "Members Only Mondays."
Avoid using all-caps on the FB status updates. The Facebook page is maintained by a human being who is cordially inviting, AND NOT ANNOUNCING, people to the club for special events.
Also, make like a calendar that has all the upcoming special events and on what days the club is closed. Then, make a bulleted list of all the special events under that calendar, in chronological order. Make it so people can click on each event for additional details, such as "What you should wear. What kind of music to prepare for. We are going to be serving this kind of food that we normally don't serve. etc."
If enough people go to a special event, make an online photo album that shows how much of a fucking blast it was, to make people want to go to the next special event. (It seems you guys are already doing this.)
Um...Hmm...what else. Idk. That's all I have for now.
