Nice shot, tough for me to capture birds. It looks like the photo is underexposed. The eagle is a little too centered, Moving the frame over to the left a liitle should improve composition.
This photo is a bit busy for me. I would have zoomed in and filled the frame with just the eagle, all the branches really take away from the photo, and paid extra attention to the exposure. You have no detail in both the shadows and highlights in the photo.
Also, I dont believe this photo really captures the theme of the challenge.
Shooting up into a bright sky is always goinf to fool the exposure meter. You have lost much of the detail in the feathers, producing a semi-silhouette and the angle is particularly unflattering.
Lots of "purple artifacts" on the branches. Focus looks very soft also.
I don't quite understand what you tried to say with this one. I can't get the link to the subject of the challenge.
