Technical issues for me too...

[marinod78300723]

Another image of mine discarded, this time has been for technical issues. I can't figure how it's possible, as far I can see in this image it seems there's nothing wrong and I will really appreciate any suggestion to understand this matter.

Nice picture. Maybe it's discarded because of some dust on your camera sensor? You can see it on the left in the sky close to the plants.

[marinod78300723]

Yes it may be... even though is very hard to see, I missed to correct right because in this picture the dots of dust are less than in other pics, just the one you've seen.
In this case I think it is a matter of post production and some chromatic aberration on the poles and columns.
Thank you again!

This one has different cause of problem but similar results. File is huge because of large editing done on image. Sky is very bad and a lot of aberration is visible even without zoom. Some pixelization in shadows as well. 
We recommend to check images using the zoom at 100% before sending them to revision

[marinod78300723]

Yes indeed I agree with you. I edited the image with the Nik Collection Software, I didn't look at aberration. This software is too much invasive. After some answers here I reprocessed the image in Lightroom 6, cleaned the sensor spots, removed the chromatic aberration. I was too much superficial sending files, now I'm more aware about all this matter.

Thanks a lot.

You are welcome

My guess is that it is too "cool."  White balance issue.  Mine got rejected for the same reason.  But nice photo.  I'd buy it.

Yes may be also that. Many thanks for your appreciation!
