Hey Stuart, neat species...I love the red "mask". Good BG. I too like the light on the subject, but I really wish the perch was better lit rather than in shade. I also would prefer a bit more of a head turn our way (although I realize this guy is probably twisted around close to its maximum limit:)). An option would be to crop additionally left and top. Good job on the branch removal...I never would have guessed it!
Nice Stu. Maybe a tad more saturation and a bit of selective sharpening on the eye.
Randy, these guys indeed have very strange irises. Ditto crop suggestion.
