They look great! You might try some dehaze on the carapaces. It could bring out some detail there. I’ve never seen turtles looking this aggressive with each other…unless it was just a tete a tete.
Karl, this is a fine face-to-face view. The reflections and ripples in the water add a lot of interest. The colors are very realistic. It’s easy to see why someone would want a print (metal should hold the bright areas and contrast well).
