Stunning bird with nice perch. Good angle, bird sharp. I have two crits: the green bird against a similar BG disappears a bit, maybe a masked layer for BG and reduce sat on greens. You have over sharpened it a bit.
Thanks for comments Marina, Sidharth and Andre. Will tone down the sharpening.
Andre, Mkhombo Dam Nature Reserve (or Rhenosterkop Dam) is about 2 hours north of Johannesburg (very near to the town of Libangene).
