Hi Radical Righteous,
If I'm correct, you can do the approach and start the conversation but you can't maintain the flow. right? Here's what I think you should do. Now Amazing Art just gave you a good example of the way to talk about think. Yes, be descriptive.
You should watch a lot of movies and music, those are good things to talk about when meeting people. Learn the art of story telling, you could tell her the story of a movie that you liked to her to keep up the conversation and always be fun to be around. No one wants to be with a guy who can't be fun. Be hilarious, hilarious as if you were with a friend, do the cocky-comedy..
Notice the little things about her like her chain, dress and hair. And share you stories, stuffs about your view on fashion etc.
Read a lot of book, facts and stuffs. You'll never run out of stuffs to say.. Imagine you're with a friend or you two are out somewhere. It isn't necessary to always engage in a conversation with her or you should be doing a never ending conversation with her. If you were with a friend and you two didn't talk for like half an hour, playing games or stuffs or while eating, nothings gonna happen in your relationship with your friend 'cause there is already a connect. So, first create a connection and the conversation will come natural to you. The first five minutes is the crucial, that the time you should take to get the attention and establish a connection.
When you open be confident. The easiest way is to have an attitude that you care less about the outcome like win or loose, you're gonna have fun and if you screwed up, you only learned more.. lost nothing.
More on getting topics. When your minds goes blank, Ask her questions relating to what she said on the previous reply. And add your share. Always ask open ended question 'cause the next question lies in her answer and if you do the yes-no type, it's gonna be hard to come up with the next one in certain situations. You can use the Yes/No type to check her interest, if she ask you back, she interested else, be more fun. These are all I can think of SPAM, I'll add when the rest comes to my mind, hopefully.
