I like the image as presented in landscape, it would I am sure, have been tempting to go portrait mode but the inclusion of the grass on the LHS is a nice touch. I might have been tempted to crop say 5mm off the base.
I like the framing here. The perch is interesting as well. The light is very nice. Love the color on the bird. Check out Okavango River of Dreams. It's a nature doc about the Okavango Delta.
Great bird and setting/perch, but the strong side-lighting makes for unattractive shadows throughout. Details on the bird look good given the loose crop.
