Photos declined for technical issues

Hello.  I recently had three photos declined for "technical issues." It was recommended I ask for feedback in this forum.  Thank you in advance.

Hello,

Were these pics taken with a smartphone?

The quality isn't very good when viewed at 100% or more. (You need to view at least 100% to check for defects in the picture.) In your case when doing so, the pixels are becoming smudged.

Have a read of this from Adobe about how to create better photos:

View youir photos at > 200%. The first has a noisy sky and halo on the tree line. The secon has artifacts around the wires. The third is not sharp and has too much white sky.

I'm new to photography.  I took the mountain photo with an Android, and the other two with a DSLR.  I appreciate your feedback.  I'm learning as I go.
