Hello and welcome
I like your first impression. As for the few questions you've outlined - you are good looking, so girls see you as valuable before you even open your mouth. This is already very big. It also means that it will be difficult for you to apply some concepts of Game. It's a bit different, and I'd recommend to watch the negging and C&F.
As far as not reading signs - you are absolutely right. She's ready for you to make a move. If you cannot read the signs, you'll most likely miss a window of opportunity and she'll get the idea that you're not the man she thought you were. It's exactly like failing a shit-test. I'm not telling you to start grinding them instantly (though it's not that bad of an idea

), but you have to lead the interaction. No amount of flirtiness, humor or looks will ever work unless you have the balls to lead the interaction and move it forward.
Send me a PM if you want to meet up.
