Quality Issues, Asking for your critique :)

Hello to everyone in this forum,

I was very proud of a drone shot I made in summer and wanted to test if it could be shared as stock image on Adobe Stock. Sadly, it didn't meet quality requirements. 

Can someone maybe help me with what I did wrong and how I could achieve  future images like this one to meet quality standards?

In hindsight, I may have overdone the saturation, so I will also share the original image for you to see if my hasty editing was the issue or the picture itself.

Thank you very much in advance,

Michael
