I was one of your 8s. I think the composition is interesting, with the steps(?) on the left and water curling around it. "freezing" the motion of the water was a good decision, as its shape is fascinating.
Too much detail lacking to my eye - perhaps processing to keep control of the highlights in the stone, or maybe just more shutter speed needed, I think. The diagonal makes for a strong composition for the required crop, however, which shows good vision.
