Nice obsevation to find this one! in hindsight, maybe the shadow of the other plant out of frame at the LHS top is the only thing that is distracting in this otherwise gr8 shot. Love it! have you looked at a B/w conversion?
this is an incredible image. though i think i would have liked it moved to the right a bit more. removing some of that spotty sand and letting more of the image over by the arc.
