In my humble opinion, it could be the moon, or a ball of concrete. Too flat, dull light. I believe you chose a subject that is out of the reach of your camera's capabilities.
The moon has several problems that I see. Around the whole edge is a "border" circle, most pronounced at the bottom. Then there's the odd, small dark blotches in the darker areas of the moon. Plus the moon seems overall grainy. Maybe a little less digital zoom would have helped. 6 Swash
Good shot of a full moon - perhaps would have liked to see a tiny bit more contrast. The main thing that is lacking, though is a link to "your corner of the world". It would have been nice to see how this image relates to you somehow - perhaps you're a keen astronomer. That might have been shown by including a telescope. 7 - floyd
