Hi,
Here are two images I would appreciate help with.

http://imageshack.us/g/9/p1050950copysmall.jpg/

I submitted them as part of my shutterstock application and they were rejected as 'Poor or uneven lighting, or shadows. White balance may be incorrect.'

I would have been OK if the rejection had been something like, 'fake plastic gold coins are fake' but the lighting on these was something I had actually spent two or three days tweaking to get perfect, shooting many dozens of images to get a setup I liked.

The idea behind these was to use reflections to make the piggy appear shiny and 3D as opposed to the somewhat flat white shape it appears in real life.

These images have been accepted at every other stock site I've sent them to. I am not sure what I am supposed to do differently on these?

Thanks for your help!
