- the tower is leaning
- the feather shot is marred by distracting white posts
- the building has power cables and another object in the top corner
Second: Same camera same processing problems:
By now you know it: wrong composition. You need to get the whole bird's feather in the picture. And you need to take care of the artefacts:
There are other defects that all by itself lead to a refusal.
Fourth: Oversaturated, grainy and bad overall composition. In addition, you should photoshop disturbing elements out of the view:
No need to start with this picture, it is anyhow doomed.
