Picture rejected for techincal issues

Hello,

A few things:

• Colour balance isn't good
• Burnt out area on the water and in the background. The background is distracting I think, so the composition could be improved
• And as mentioned - underexposed - the fish (?) is rather a blob of black - there is little detail.

El iso tan alto te ha producido mucho ruido, y sobre todo el principal problema es el  foco  del agua que te a a producido una luz quemada y mucha aberracion cromatica en el agua, esto te pasa por tener una fuente de luz frotal a la camara.

As @George_F said, the artwork will require a signed release by the artist.  When you submit assets to Stock, you're submitting images for commercial use.

I also believe if the technical issues are fixed, this would get an IP rejection unless there is a property release.

The histogram reflects underexposure, and it looks underexposed to me as well.  When correcting for the underexposure, noticeable noise appears in the image, I'm assuming from using iso 1600.  There are parts of the main subject that are out of focus.

I hope that helps!
