There's a lot to take into concern here(body language, her current mood at that time and place), but overall
i think you did a great job! Really encouraging both sexes to approach. However, i would recommend that you take a closer look into the word "date". It's both outdated and predictable of what it includes. (As u may have noticed, my English isn't that great, sry for that). Anyhow, dating pretty much implies that at least one of you have to engage physically sometime when meeting. This puts some kind of pressure and prediction on the both of you(also, date usually makes u think about money and expenses, imo). I would suggest that you instead ask girls to 'hang out' with you. This relieves a lot of unnecessary tension and it means that anything can happen!
hope u understood at least some of what i said
