Pat I like them all especially since you tried something a little out of your element! The leveled/cropped versions are the best.
So how do you deal with the highlights? Well you can in post somewhat with a brush and the highlight slider and exposure slider over the brightest areas.
When shooting you can use a circular polarizing filter to get rid of some of the glare but watch out for oversaturating the sky and other colors.
So here is the hard part when you are on vacation or visiting an area with your camera. If you can only shoot during mid day then you have to do the best you can or hope for a little cloud cover. Otherwise you have to be there with your tripod at sunrise or sunset. Theses scenes would have much different lighting without the strong "contrasty" elements.
All the tones would be just about equal and the image would turn out much more vibrant. You also have the ability to use slow shutter speeds when the light is low, to add some texture (to your liking) to the water. Not everybody can take the time away from friends and family to be at a site at O Dark Hundred so you do what you can. I think landscapes can be challenging enough without fighting the light so at midday I enjoy the view and take shots if I can't come back. If there is a waterfall involved I try my best to get back there during the "golden" hour or even later.
I love the WF shot and really enjoy spots like that.
Great work. Post some more!
