I'd like to see a little less foreground, perhaps a little lower point of view where the ocotillo stands out more and a level horizon line. That being said, this is a great sky, nice subject matter and a really nice location. Not too far from the New Braunfels/Canyon Lake area if that is where you live. Bill Barber
Love the sky. I'm not so sure the horizon is level in the Big Bend. If you're running a red filter, you just might be able to pop some fill flash on the ocotillo to bring it out from the background without blowing out your foreground. A neutral density gradient filter might also help get a better balance between the foreground and the sky.
