You have shown us that you were in a beautiful place. But, I do not see these as "wow" photos. First, this is not meant as an insult, but rather it is more of an issue I have been struggling with in my own attempts at landscapes. How can we make similar images (i have plenty like these taken on hikes) that are more than just a documentary of where we have been?
When faced with a large beautiful landscape, how do we find that picture within the picture? In your middle photo, 302, I think you have come the closest. You have isolated a scene. We know your main subject was the falls. The large tree helps with depth. The colors are sharp. The focus is clear throughout. you have framed the falls with the trees nicely.
Now how about #304? From my comments you might think I prefer the cropped version, but I am not bothered by the original. The trees in the foreground are important elements because I think they add depth, but would even like them better if they had been closer. Notice how the top of one of them ( I wish I could look at the image at the same time I am writing) is touching the background. I think it would help if there was a gap between the top of the tree and the land in the background. This is a small point. In fact, I am not really certain why I do not find this a "wow' composition!
in 304, I think you have tried to include too much. What is that you really want us to look at? Sky? Mountain cliff? Waterfall, riverbank? See what I mean? I would really like to se that waterfall! What emotion do you want us to experience when we look at that image. I just see some more mountain scenery, but Iwant to see more of up close and personal.
I think the images in the thread entitled "Still down by the river" is what I am looking for, or better examples of what I would like to see in my own photos.
