This is a stunning scene, however I feel that the exposure may be a little bit bright for the parts that are sunlit; I'm assuming that the exposure was made slow in order to blur the water, but I would bring it all back down in post-production by maybe another 1/2 stop or so. Also, the people in the corner don't bother me that much; they give a sense of scale if anything. However, one of them is sitting down which kinda makes their presence a little bit unexciting; it might have been optimal if they were all standing together enjoying the view of the lake and the falls...

Hope this feedback helps!

I think a longer lens could help pick out some of the details. There's just a little too much going on for my eyes to settle on one thing.
Looks like a nice location, though.
