Ronny, I know this location well, and live close to the three New Mexico sites you photographed. You have some very nice shots on your website.
Three Rivers Petroglyphs is challenging to photograph because of the usual extreme contrast resulting from deep shadows. You avoided this problem nicely by using late afternoon sun.
There are a couple of things about this particular panoramic composition that are not quite satisfactory to me. The first is that the image opens up to the right and my eye wanders out of the picture. I would have tried to move to the left and used the big foreground rock and the mid-ground hill to close the right side of the frame, and/or cropped closer to the hill.
The other problem I see is that the panorama successfully captures the immensity of the mid-ground plain, but inevitably diminishes the grandeur of the distant mountain range in the right half of the image: it rises to 10,000 feet. (The range on the left is much closer and I estimate is 5,500-6000 feet tall.) I have tried some landscapes of this view, but avoided the panoramic approach because of the loss of proportion that results. Instead, I used a more normal lense to capture striking petroglyphs in the foreground,(adding interest to the rocks) and to emphasize the mountains more fully. Also, by using a lower elevation, I was able to de-emphasize the plain and so emphasize the mountain range, which I though resulted in more powerful images.
Your photographs "Three Rivers Petroglyph" and "Petroglyph and Bush" are more satisfying to me and are close to what I just tried to describe.
Even wide-angle shots are usually disappointing in wide-open country like this, because the camera often does not capture what seems grand to the eye.
I realize you were probably only there for part of a day, whereas it took me many attempts over the years to create a landscape that satisfied me. You have a great portfolio for a short visit.
