Interesting topic and image
I was always fascinated by the fact that nature’s harmony is far more complex than humans would expect. Just look at finite simple groups classification. The reality is not always as simple as we would like, or as our perception is build. But even with our oversimplified view, the nebulas are still beatiful, aren’t they?
Some less intriguing droplets examples:
The bokeh in pink-blue photos was too busy, and I had to calm it down with strongly negative microcontrast, counteracting with some fine contrast. It would be nice, if I could use fine-contrast sliders only for specific hue ranges…
How did you find the right moment?
Randomly 
Honestly, hard to say, but I had some experience before with fast action photos which were better single-shot rather than using serial shots. You just learn to feel when the drop fails and know your brain latency. The photos were taken some 15 years ago with D700 (12mp) + 105/2.8 Macro + SB-800 with shutter speed = 1/8000 sec, ISO 800, f/32, AF manual. I was learning my new camera then.
Of course, there are millions of better droplet photos around. See for example
