Wow, you really captured the “spectacularity” of that falls, @izzyb! Great first attempt at silky water. Like @bennett-family said, sometimes a slower shutter speed will make the silky water effect look more intentional. I do like being able to see the texture in this falls, especially the texture at the bottom, and you don’t want it to look like a blank white sheet (which it might look like with a super long shutter speed with all that water).
For me, I keep 1/10th in the back of my head as a fastest possible starting point and that usually gets the water looking silky at close range. When the water is farther away, longer shutter speeds are necessary to get the same effect. Just try different speeds until you come up with the one that looks best! For this one I probably would go with something longer.
The orchid is so pretty. Sharp, colorful, great background blur. I probably would have tried removing that other pedal that is in focus in the bottom left corner. The color scheme is great, though I may have warmed it up just a hair.
