Photo rejected, any thoughts as to why?

Hello,

Unfortunately, the sun is a problem. Exposure issues:

It has ended up being a white blob. Adobe will reject this, based on this alone!

I suppose it was taken with a smartphone. It is difficult to capture such a wide range of brightness and to get everything well exposed. 

• Foreground is underexposed (too dark).
• Tilted horizon.
• Sun is a blown out blob. 

Pointing your camera directly at the sun is a good way to burn-out sensitive camera sensors.

Also, you’re competing with over 33 million sunsets in Stock. That puts your sales potential from this very low.

The shadows are underexposed and the overexposed highlights of the sun are completely without detail. Also, the foreground is too much of the photo and adds nothing to the subjects, 
I would change to a landscape format and fill in the sun.
 

The shadows could be opened up and the wooden structure in front is distracting.
