Hi Guys,

Really need someone who succeeded with the initial application at iStock with 3d images.
I do concept stuff, lots of them isolated on white and all in 3d. I tried once, but I was rejected.
As you can guess, iStock needs to see a lot more diversity, so I am preparing some images especially for this application.

My first try was a couple of months ago and since then I am reading books, forums, blogs, etc, etc...just to do things right and avoid another rejection. 
I am preparing a concept, an interior design and a exterior with satellite dishes and a base station. I have some other ideas for a backup. I am considering posting them here for critique as soon as I finish them.

Meanwhile, I was wondering if I could find here someone who succeeded with 3d in the initial application to give some advice. I'd like to learn what is most important in the initial application with 3d images besides the subject, composition and lighting. How could I impress them most?
