I like this one a lot, nice job exposing the bill, so easy to blow on these guys.
The lighting really makes the eye pop, strong sense of form. Like the gently undulating water, blue highlights, slight blue tint to coots blacks.
The only downside to the wavy water is a messy reflection, which of course you had no control of. To lessen the reflections impact, I would consider toning down its luminosity , esp the bill.
Sweet light and I'm enjoying the rich details. Exposure looks great - easy to blow the whites on the beak. The water is special here with those blue highlights. Nice work Dan.
