Here is a nice little bird I met in Yucatan a week ago. I set in the water and waited until the flock of bird came back, so I could let them come to the minimum focusing distance of the lens. Thank for looking.

Lovely behavior and low angle. I would clone out all the catchlights but one. The light looks a bit harsh, but you did a good job handling it. IMO it seems like fine feather detail is a bit lacking. I love the water droplets.
