Help with Identifying quality issues (no AI)

Hi there! I've had a few of my own images rejected for quality issues.

I'm looking for some feedback as to why. 

this is the general message it said: 

"Thanks for giving us the chance to consider your image. Unfortunately, this image doesn't meet our quality standards so we can’t accept it into our collection.

Common issues that can impact the technical quality of images include exposure issues, soft focus, excessive filtering or artifacts/noise. Learn more about our technical requirements here."
