Russian Tortoise Shots

I was wondering if I could get some C&C on these shots I took of my friend's tortoises? I've done some PP work on all of them, including some HDR work of varying intensity on each.

Interesting!
#1 I would crop the grass in the foreground out, although it seems the focus fell on the grass and not on the turtles.
#2 Love the bokeh in the background. I see some noise under the turtle's belly and notice the chop on it's right (looking at the photo) leg.
#3 Looks like the focus is on the dirt.
#4 Focus fell on the grass and the left (looking at photo) turtle. Right turtle is out of focus.
