I slowly poke my head above the parapet...
R5 EF600f4 2x III HH
1/500 f9 iso6400 -0.7ev
PS2021 Cropped from horizontal, near FF vertical.
Cloned a couple of part leaves lower RHS.
Hopefully the eye wins over the leaves lower front.
Levels, NR to BG only, Removed heavy blue shade cast.
Nice and sharp - looks good with the 2x. Pretty slow shutter, but it seems to have been enough here. The yellow eye is great but too close to the left hand edge of the frame. I would try shifting the crop to give the face/bird more breathing room.
