My photo got rejected, can you tell me the issues?

The foreground is overexposed.

Overexposed. Is your subject the fish? If so, then your photo is poorly cropped.

Hey ​@belindamora1015 

The image a bit to centred. A prospective buyer probably wants a bit of space to add content/ copy. You could pop this image into PS and extend the image to the left or right using the gen fill option.

When submitting images ask yourself these Qs:
Who is going to buy this image? meaning who is your target audience and what purpose will this image serve?
Where would this image be used? What company or type of person is going to buy this image?
When have i seen an image like the one I m submitting been seen besides a social media post? or when would this image be used in a commercial setting?

Adobe stock is not a social media platform. My meaning is Stock images are often used in a commercial/ profession setting. People take a bit of time to clean up their images to ensure they meet the commercial value expected of Stock sites.

Finally, how would a prospective buyer use the image?

Cheers

Overexposed highlights for one.
