Nice stuff, I feel pretty much the same way as previous posters.
Quibbles: in the first one there is some oblong object visible in the mist, more or less a horizontal line in the middle of that soft cloud. I find it distracting, and wish it either were not there, or made itself more obvious (I don't know what it is). The light feels a little strange, the foreground is very dark and moody but the falls and mist seem to be more or less well lit. These feel a bit like looking out of a cave, but I don't think we are.
I propose no "solutions" to these remarks, I merely note them as features of the images that make me feel uncomfortable.
I am fascinated by photographs which rob me of a sense of scale. How close is the stuff in the foreground? It feels sort of like puddles at our feet, but for all I know they are vast pools 100 yards away. This inability to tell scale is a positive, for me.
