Looking for critique of this one. The slide is a little more impactful than the jpg, but I want to get responses before altering it. I am interested in critique of the whole image, but particularly I am looking for: 1.) It's impact or lack thereof on you, the viewer, 2.) on your screen and to your eyes is the subject (cactus) clear enough or does it get lost in the sky.

Thanks for any and all feedback!
