Ah, look at all those good head angles. Good comp. Good exposure and details. If mine I'd likely get rid of the darker areas along the top, but all else looks good to me.
I really love the way the black water and background make the birds pop in this image William and the silver ripples and reflections on the water counterpoint nicely with the pure white of the adult birds. I suspect it would make a stunning B&W.
Nice shot Will I would suggest the swan on the left is a little dark and contrasting in the head and neck, I have taken the liberty of modifying, I made a selection of the head and neck then made an Adjustment layer, Levels and adjusted the RHS slider to 243 and the central to 1.46
