Hi from the Critique Club!
I like the idea behind your entry and I think that it fits the challenge well. You've made a good job of 'freezing' the water with a fast shutter speed. I don't feel that the main water flow is sufficiently sharp to grab attention, and like other commenters, I find the background distracting. I think it's definitely something you should work on, with different lighting, backgrounds, composition etc You've got the basic structure it just needs some polish - I look forward to seeing more!
Very abstract with interesting OOF highlights. Not really seeing this as a defined twisted or curved lines that is appealing (to me). If the challenge was 'Water' or 'Splash' then I could buy into it. Sorry. All JMO of course. Good luck in the challenge.

Great sharpness for a water shot. That can be tough to achieve, I like the bokeh too. Overall the shot lacks oomph or a story and anything to really grab onto. But the technicals are fantastic.
