Allen, I think your framing works very well. Having a fair number of red-eared slider shots in my files, I’m impressed with how big and red it’s “ear” is. The turtle’s reflection and the ability to see through the water are fine additions.
I think your framing is fine Allen. I like being able to see the shell patterns under the water in this through the reflection too. It looks like the turtle has turned it’s head sideways from the shell to look around a little. I like the leathery detail in the head and your red and yellow colors look really good.
Very interesting subject in the cool environment.
For me, surrounding environment decides the composition, that way it works fine.
I may selectively saturate the red here.
