Razones de rechazo

There are typical artefacts for phone portrait pictures:

The in Phone processing tries to give that nice DOF view of portraits, but they mostly fail and introduce artefacts. They look great in small on your phone screen, but seen at 100% and 200%, you see the defects. Do not use that option if you want to take pictures for stock.

Other defects are easy to correct: lift the shadows a bit, add some contrast.

Unfortunately, the picture is lost as this.
