both of the shots you posted are not very sharp, and are lacking in contrast or something. with the way it was exposed the water feels a little muddy, but at the same time. one thing to consider about these kinds of shots is how much time is spent in post usually, and how much care is taken on individual areas of the photograph. the improvments that can be made by putting in that effort is evident by the edited edition of your shot that was posted.
they both have a nice kind of diagonal flow to them, which i almost always like, and like it here.
overall they seem crowded, with alot of water in them, and that competes with the rocks and other stuff in the frame, maybe if you had backed up or gotten closer they could be better.
All of that aside i think they both have potential and are not bad! your on the right track compositionally, and with more careful post work that they can both be improved. more importantly with more interesting light, or more dramatic focus, or something - a shot like either one of these can be GREAT.
