Even this one qualifies you to shoot for National Geographic! :) Great fisheye perspective.
I think you were lucky to get away with this shot - that was no tortoise but a Teenage Mutant Ninjan Turtle about to attack you. Be careful while walking across the park. :)
Thanks James, knew you'd like that. Will contact National Geographic and tell them about my discovery ;).Thanks for the warning Yesbuts, will keep this in mind and stay away from any Teenage Mutant Ninja Turtles and mutant rats who might be their sensei :D.
