In your first rendition of the eagle, I was going to recommend cropping off the bright diagonal rock, because it seems to intrude and is too bright. Otherwise, I really like the lighting, the exposure and tonal range. It's an excellent nature shot.
However, when you tried the PopGlow, it seems to have caused the highlights in the top of his head to blow out completely. So, to that extent, I don't like it nearly as well as your initial version.
I love your waterfall, and I would not apologize regarding the "misty" quality of most waterfall shots. I like this one very much. The only thing I might have done differently would be to change my position right or left and change the angle of the shot accordingly in order to get the main falls off center a bit.
Great shots - congratulations!
