Girls notice every single little detail. At times, it's like they're robots. Like I said, you can get away with more with young girls (or dumb girls, or drunk girls), but a quality lady of any age is bound to be obscenely clever with social situations. You also mentioned that you rarely make eye contact. No matter who you are, that will bug people. There's very little that gets under my skin farther than people who won't look me in the eye or shake my hand. Everyone notices things like that. Same as smiling. Nobody cares if you can talk about interesting things if you make them uncomfortable with bad composure and a lack of eye contact. A good conversationalist knows that they merely need to direct the conversation subtly and let the other person do all heavy lifting. Everyone loves to talk, even moreso about themselves. If you get a conversation where you're speaking 30-40% of the time and the other is 60-70%, you're golden, Ponyboy. Pulled those percents out of thin air, but you read me. If a girl finds you charming, none of what you said matters. it works for me, so whatever.
