Really like the first one; the rest do nothing for me.
I see a saguaro in the background in #1; did you see any instances where an ironwood tree, a mesquite tree or palo verde is up over a small saguaro? It provides the necessary shade for the saguaro to thrive. It's called a nursery tree and as the saguaro grows, the saguaro takes all the water that the nursery tree would get and the nursery tree dies. You'll see a lot of instances of that situation in the desert.
In case you didn't notice, I was raised in Tucson and after 40 years of living in other states, my husband and I have retired here
