Rechazo por razones tecnicas

It's a nice dog picture, but unfortunately, it's not usable for stock:

• Nothing in this picture is sharp. That's not recoverable. The dog should have been in-focus.
• The white balance is too cool, the dog's fur has a bluish tint.
• I suppose you tried to sharpen the image, as I see typical sharpening artefacts.
• It may well be, that the compression artefacts here have been introduced by uploading the image to the forum. If they are present in the original image, that would also constitute a defect.

there is arbetration between the sky and the trees. The foto is not focused properly and there is too much saturation.
