I don't think you have maximised the potential of this shot, as it is small and could have done with resizing to 640 on the long side. But if that was done I think it would have pulled out that this is quite grainy and doesn't seem well focused.
For me, I would have liked a little sharper image. Also, the intersection between the centre cactus and the horizon gives this image a staic feel for me. It sort of prevents my eyes eyes from exploring the whole image. JMO
This picture is very 'flat' (no contrast, because of the rain I guess). There is not much of interest and the colours does not stand out. Your camera/lens gives some vignetting which is not very pleasing. All this imo, obviously. Good luck!
Rain in the desert is a remarkable thing. (I lived there for 20 years.)
Your image looks a little blurry, perhaps a tripod, and a longer exposure at lower ISO could have cleared and lightened this up a bit.
This isn't a very flattering shot. Focus is off, coloring is dull, it's busy and compositionally flat. You've got vignetting in the corners as well, something to watch for. Also, smaller images tend to do poorly automatically.
This is truly how our desert should be photographed and displayed!!
All natural-I can almost smell the monsoon breeze. Thank you for capturing the sure elegance of the sonoran desert-WONDERFUL!!!
Walk up a few steps and put that cactus in the foreground for a more dramatic photo. The dead center horizon splits the frame in half. It will be more interesting with the horizon on a third. Crop this shot in half way and up from the bottom leaving the tallest cactus in the lower left of the frame and you will see what I mean. Nice spot and interesting lighting.
