Many approach indicators, help!

Usually when im on the clubs I have lot of eyecontact when I walk past dancing girls. Or sometimes girls stop front of me or they walk near me that I would see them. Sometimes when Im dancing I see approach indicators.

How should I open when I get approach indicators? Is whaddup good enough?

How should I approach if girls back is towards me or face is towards me? (sometimes they are glancing over their shoulder) How should I "open" when dancing?

How should my body be when I approach? I don't wanna be creepy and scare them...

I want know tips kthx...

Everyone opens their own way keep that in mind. Whe. Stuff like that happens to me and I get lots of eye contact from one woman if she is already close enough to talk to I might say something like " if you wanted to talk all you had to do is say hello" throws it in their court but the door is wide open for communication
