Rejected due to poor image quality

• Compare your work with other Stock inventory.  Is it as good or better than what's represented?
• Who will buy this image? 
• What will they use it for commercially?
• Would you buy it?

These are important questions to ask before you submit.

Hi,

From what I can see:

• Not sharp enough
• Not enough detail in the shadows
• Light halo around the tree
• Crooked (horizon not level)
• Colors don't "pop"

It appears to have been taken with a cell phone or tablet, which will be very challenging to use for stock photography (although it is usually possible to use a phone/tablet, if you work within the devices limits).

Aside from the technical flaws, you would also need to submit a model release for each of the people sitting on the bench.
