There are many ways to do street photography, you can choose not to focus on people's faces and depending on the composition that can be very interesting. There are shots where you necessarily have to focus on a person's expressions to compose according to their emotions and what they are doing. Either of the two is very good and here you have shown it to be wonderful 😍
I also totally know and understand what you mention about privacy :)
I noticed you used the 18-55mm kit lens. One more point in your favor that you have a beautiful photographic eye for street photography.
