Nice flow image. I'm either try to get stop action on the water or a nice smooth flow pattern. Neutral density and/or polarizer filters are good for getting extended exposure times without overexposing te image.
Good challenge interpretation and very, very accurate. You have to have some understanding of and respect for a harsh environment like the Sonoran desert in summer. Forget that and you will get in trouble fast. I did everything possible to minimize the dangers... I went "with the flow" - Steve
Good composition.
Border IMO is too heavy.
Light at top of photo gets cut off either by cropping or original.
Steve loves nature photography so meets challenge well.
It's a bit of a stretch for the challenge description, but is such a great shot I'm not sure it matters. :) The tones in the image are cool and calming, and the flowing water give a feeling of serenity.
