Another failure after i tried to initiate conversation with another foreign woman today. Was it weird of me btw?

Today i again came to this really posh area of my city Bangalore in India to eat in this Art Cafe. After eating, i was exploring the streets there. That's one of the most posh area of the city having big luxurious hotels, a huge shopping complex, IT companies, fancy restaurants, cafes, pubs and people having expensive luxurious cars. There were several foreigners in the area who probably works in the IT companies there. Suddenly i saw this white Caucasian woman walking who is definitely an expat too. She looked to be 27+ in age and wearing glasses just like me and is pretty too and I am 23 and an MBA student now and a nerdy looking Bengali Indian guy. I said her excuse me and she even looked at me once but suddenly i became nervous and just smiled a bit and waved my hand at her. She then continued walking so we didnt have any conversation and of course i didnt try to initiate conversations further just to respect her space. It sucks that I am still kinda shy near women and have a hard time initiating conversation with them. Was it really weird of me btw?
