If, as you say, the motif you like is the repeated image within the glasses, then look at this again: "What is needed" and what is not?" Just imagine this "
what is needed" is a
person. What is the minimum material needed to define this "
person" with the qualities you admire?
I think you were entirely correct in choosing this subject. There's fascination there. If it was a cat, a child or a person you'd know immediately what the whole thing is and what of that you must include. Maybe this way of looking at what you aimed your camera will allow you to revisit your ideas of what to rank as the essence of your inspiration and the core of what you might need to show.
"What you might not need to show, or show in the same clear way?", is the tougher question you must answer too!
