“Humans” can cover a lot of different ground and style…..
I did hear a quote once that was in reference to a photograph of an elderly couple holding hands and you could see both wedding rings: “Most pictures capture a moment in time, this on captures a whole lifetime in a moment”.
Perhaps with some people watching at your local venues and some heartfelt prayer and meditation, you’ll find that inspiration that has been eluding you.
I wish you the best in your endeavors! Sorry I couldn’t provide you the inspiration!
