Can anyone help me to indentify the technical issue of my photo? I feel like it's quiet decent thou

Besides @Ricky336's correct assessments:

...98: has chromatic aberration and is noisy.

...15: Dust particles, on the sensor or on the lens:

I've seen those also at other locations.

...84: Either the camera pole was moving due to wind, or you had camera shake. In Addition, if the object had been in-focus, you would have seen the logo and that would have been an IP refusal.

Hello,

1st picture - out of focus, 2nd the sun has created a white 'blob - it's difficult to get sun photos looking good, and the 3rd photo, also out of focus. Your pictures are unfortunately not sharp.
