funny this one ! Nicely exposed frame. Nice moment with all of them dipping their heads in at the same time. Normally we choose low angles but in this case the angle u've chosen is apt since a lower angle wud've blocked the birds in the second row.
Wish u'd been more careful while blurring the water. The areas bordering the birds & water show some discrepancies. That apart, the water lying in the focal plane of the birds *would* also technically remain sharp & in focus.
