Hi Jimmy and Dave,
Nice work with my shot. I agree that my shot looks over-exposed by comparison to your shots. One thing that bothers me about the composition is all of the 'mashed' ground around the boulder.
As to the intent of the composition, I wanted to see if I could get the race track playa in the background in the composition and keep it there. I have many different shots focusing solely on the rock and ground around it, and I wanted to try something different.
The one thing about Jimmy's shot, for me, is that it looks under-exposed where mine was over-exposed. Dave's shot looks more accurate...but LOL, now that I am seeing all three of them together, I am just not happy with the shot as a whole.
