Hi John - The head angles really work here. Glad they cooperated and all generally faced the same way and then the one facing you. The pano works but I would go even further taking about half the space above. Less distractions that way and really draws the eye to the turtles. You handled the harsh light well.
Just one little twist of the head and you have perfect head angles on these John,must say I agree with Rachel re the pano ang loosing some from the top and maybe even a little from the bottom,great the way you have caught these.
