Hi Keith, you present an interesting perspective here with the red reflection. In my opinion, if the Heron had moved his head towards you, it would havd had more impact.
Very similar to our bird, just a bit lighter.
Hi Keith !!! As presented would try cropping the reflection and placing the bird more to the lower left corner When you can get a perfect reflection its good to include this looks dark
Not sure if its a crop or processing but your Mk3 can bring out much more in the feather detail Looking at the image the light does not seem harsh but the image looks contrasty Also a lower angle is always good but doesn't look like it was advisable in this instance !!!!
