Hi Allen, I like it too, so going to check out my shots from Saguaro NP years ago . I had to look it up and think its a California barrel cactus, which will flower up top. I know it takes years for these things to grow so wondering how old this guy (and offspring) are. Centering them works well here, along with the portrait orientation. Lots of needle details and the backlighting is a nice highlight. You didn’t fill the frame, and so some interesting environmental details are shown. Overall nice work!
I like this, Allen! It has the same feeling as a parent & child wildlife photo. The shape of the cactus makes the centered composition work quite well.
