What was the actual rejection reason?
Was it Technical Issues or IP?
I suspect IP due to the fact you have the 'Champion' wording on it.
Reason listed was technical issues, surprised me. When I first saw it got rejected, I also assumed it was becasue of the logo
In your experience, does Adobe ever mislabel this? Maybe it was because of the logo?
Well, in this case after looking more closely you have noise and chromatic aberration.
Purple fringing on the edges and the sky shows noise:
The logo can also be another reason. The moderators do make mistakes, but they also choose just one category, even though they may also be others.
The technical issues are probably the very obvious noise levels:
and the chromatic aberration.
The logo will be an IP violation refusal. That's in addition and need to be addressed absolutely before submitting. As stated by @ricky336 , moderators can only flag one refusal reason and they will do so as soon as they see the first problem.
Next time when taking such a picture, lower your ISO. ISO800 is too much for this camera's sensor and there was really no need for a 1/4000s. So you had a lot of room for improvement. The aberration can be easily corrected in Photoshop or similar. If you did shoot raw, you can try to correct the noise without loosing to much detail (colour noise is not as much a problem as luminar noise). Playing a little bit with the parameters may save the image. Even with the JPEG as submitted here, I could do a good deal of the recover (reducing colour noise, reducing luminar noise, adding some sharpening, removing chromatic aberration) but I amplified the JPEG compression artefacts by doing so). Give it a try.
