Arizona, Organ Pipe Cactus National Monument

Excellent colour and contrast, great caci in the foreground to grab attention.

The reds, the greens, the blue/violet change in the sky, perfect!

The only negative that catches my eye (and it not a big deal), but that start just stands out and look out of focus and like it should not be there. Perhaps, and I'm really nitpicking, you could have framed the whole cactus in the foreground (though I've been there, that can be so impossible withour getting extra junk).  Easily a 9.3 out of 10.
