Refused for Technical Reason

Hello,

The background doesn't help to make the birds stand out. They are nearly the same colour. They blend into the stone. I'm unsure if sharpening will help, but perhaps cropping out the patch of blue sky will help to balance the photo a bit. I don't think though it will be clear and sharp enough for stock.

Definitely a fantastic scene to witness; however focus on the birds isn't sharp enough perhaps due to either a too-slow shutter speed or camera motion, or both. You might be able to improve the focus by applying selective sharpening to the birds.
