Had a nice chat with a girl last night, kind of froze on physical escalation/flirting

Went out with some friends last night. Ended up chatting to a friend of a friend of a friend. Practically a stranger but doesn't count as cold approach since we were kind of just stuck in the same area. Ended up chatting to her for a while, about many things, and she seemed interested.

Kind of just ended when we decided to bounce to a different club.

Now I'm wondering what could I have done to 'better' the interaction...

Some things I've been thinking I should have said or talked about (and hitting myself for not saying):

Amazing eyes;

beautiful piece of clothing;

Interesting outlook on life;

move to quieter location;

Anything else I could say to flirt or increase physical escalation?
