Nice work. I like haikus. Anything about the desert reminds me of a poem by Stephen Crane, so I'll share it with you right now!
In the Desert-
In the desert I saw a creature, naked, bestial, Who, squatting upon the ground, Held his heart in his hands, And ate of it. I said, "Is it good, friend?" "It is bitter - bitter", he answered, "But I like it Because it is bitter, And because it is my heart."
It always amazes me that when you string just the right words together in just the right order you can draw the clearest picture in a persons mind. For you first attempt at haiku (a much braver feet than I willing to take on) you did really well. Keep going you seem to have a real knack for it.
