Photo rejection due to technical issue

Hello,

From the metadata of your photos, I see you've used a Nikon Coolpix. Unfortunately, it will be hard to get a really good quality image. The sensor is small, - you get noise like in the 3rd example- you can't take raw photos, only JPEG (using JPEG makes it hard to edit well). I think the photos are fine for memory shots, you can show them on a small screen, print out to say 6"x 4", but for stock value, you won't get very far. Also for stock, the subject matter isn't very interesting.

Your problems lay with exposure, cropping and noise.
