Like the idea and that you kept the reflection in the shot (I think turtles basking on logs like this are really cute). I would have used a bit more DOF to get the top of the turtles in focus. Also it's a bit overexposed looking on my screen.
Very cute find. The use of three turtles is good and you got a good reflection. However the focus is really missed and I see no artistic reason why it would be done purposfully.
