About the Image(s)

Taken with my Nikon D 5200 on Manual Mode, Lens 55-300; Focal Length 35mm, Speed 1/1000sec., F/6.3, ISO 800. These small but mighty movers are difficult to capture sitting still. Post processing Photoshop Basic adjustments, increasing the blur on the background, trying to sharpen feathers and removing hot spots bird and flowers. I did brighten the catch light in the eye as well as mute the green background a bit. Finally, I used ON1 to reduce noise. My questions are: Does the square crop help the composition? Did my attempts at sharpening work (not too much and not too little)?
