What do you think of this situation after the first date?

I went on a 7 hour first date with a girl on Monday. The date was really good, we talked basically for the whole time and we both felt comfortable with each other the whole way through especially for a first date and also considering there’s a semi language barrier with us (I’m Australian living in Australia, the girl is from LATAM but knows English to a decent level). Since the date though her texts have been shorter with a much longer reply time too.

I asked both a guy friend and a girl friend on their thoughts. The guy friend said that I need to play it cool, don’t text back long replies (started this in the last photo) but he also said she likes me but is testing me hard right now to see if I’ll over-text/come on too desperate etc. The girl friend said she doesn’t see anything wrong with the interaction and said she thinks the girl is keen on me.

What do you think? Is it normal for a girl to pull back a bit/test a guy after a first date? Is there anything different you can see through your eyes that you think is happening here? Or am I completely overthinking the whole thing?

I uploaded some photos - First 5 photos you can see should be pre date, the others are post the date. Appreciate any thoughts, help and guidance anyone can give. Much love to you all ❤️
