Welcome to the forums, Liz!
Those are some nice falls! You did alot better at your first silky water attempt than I did on mine! It looks like it wouldn’t have hurt to have a slightly slower shutter speed – the falls look somewhat silky smooth, but I think there’s still a bit too much texture in them. I also do notice some blown out highlights above the falls, and that’s something to try to avoid. What are the specs for the image?
The orchid is quite lovely; the photo seems underexposed, so you could probably bring up the brightness.
Did you edit either photo at all?
