I would play with the crop though the bottom 1/3 of the picture to me adds nothing and takes away from the over all feeling......
For me, that circularity in the foreground is absolutely necessary, taking me around and back to all those (many!) people enjoying a leisurely evening... Then again up and around the cloud in the sky. In composition, I imagine an (elongated) infinity symbol, with people at the juncture.
Subdued, quiet, reflective, yet with energy and life. I'm intrigued.
