While your observations are probably correct, this isn't the critique forum.

I know it called Great BLUE Heron, but I think it is too much blue.

I think the WB wasn't set to the actual lights.
Even on a film where I can't set the WB the colors are not turn into this strong blue.
If the WB would have been set to the right value, the color of the reflections would be turn out much better.

Otherwise it would be a lovely picture.
