This is not an easy question at all, is it? Posting something like this doesn't demonstrate that you're an AFC, it just demonstrates a lack of general intelligence, to be honest.
Something like this is completely contextual. There's so many factors to consider, that it's not going to be possible to give an anwer to this question. The culture in which you live, the woman's upbringing, how attractive you are, how used to she is to being hit on by guys, your tone of voice, your body language, the expression on your face, etc. You see what I'm getting at? You're never going to know exactly what goes on inside a girl's mind, but how about you actually get out there and start making these approaches. At least then, you'll be able to test their reaction.
If you're an AFC as you say, the best advice I can give you is to not attempt to micro-manage your game. By that I mean, stop trying to analyse every single sentence, gesture, etc. that you make. For most approaches, the first thing you say doesn't even really matter. Most PUAs claim to not even remember what they open with most of the time. Paint your picture, but don't scrutinize every brush stroke.
