It's ok to miss, I professionally miss sometimes too, like, I don't know, people.
People do that.
But don't do that when shooting! ;-)
At least you shot some nice photos.

Istanbul always makes me think of cats. If you haven't seen it, there's a beautiful documentary called Kedi, all about Istanbul's street cats. It used to be available for free but I couldn't find it anymore. Maybe a YouTube Premium trial would do the trick, if so, watch it and cancel :-)
