Hi Alain,
I really value these pictures. Do you always use a tripod or with just two images in a stitch, are they hand held. The first picture is very well set up with the wide angle lens and that sets up the view for the distant landscape very well. The major pyramid rock helps to keep us moving through the complexity of the oversized image of the foreground rock up to the real deep landscape beyond. This image does allow us to find new routes in exploring the rock complex so it should be a good print to have.
If I was given a wish here, I'd ask for a tad more cloudscape as it seems to be getting better to the top edge.
The signature of the second picture is placed so very well that it takes on a role as a compositional component of the image! Worse, the color of the large letters are from the palette of the image which enhances its membership amongst the essential elements of the photograph itself. It could be printed just so. However, that's not the intent here, of course! Unfortunately, we do need some marking of images to deal with stealing of photographs.
I have still to work on reading this, but with no text balancing anything else or occupying serious attention. I'm interested in this picture since it raises a number of compositional challenges. Just because the scene is obviously of an awesome vista, does not mean we should overlook the many decisions that were made. This picture is no mere snap and should not be looked at in one pass. It's more complex than that in its zones of interest. So I'll return to this.
