Hi John Would leave the antenna in place, it is what it is and does show what is being done.
Would place the birds on the lower right rather than the middle of frame, giving room for the area the eagle is staring !! Always nice seeing those birds !!!
i would leave the Antenna in - adds to the story - IMHO
Agree with AL'S cropping suggestion - On my screen I might darken the mid tones just a smidgen
Fine animals. :).
