It's six months since I uploaded to istock. Half my images rejected, those that are accepted don't sell anyway, so why bother? Besides, I've had other things to do.
Weekend before last I had a model over for a shoot for my current 3d project. While she was here I decided to take a few stock oriented shots, and uploaded them to istock. Just had four notices within a few seconds (so probably all the same inspector). Two accepted, two rejected for artifacts. Same gear, same light, same processing, only the poses were different. So what else is new? Well, they won't sell anyway, so who cares?
Meanwhile, my 3d project. I'm only a couple of weeks into it, so nearly a year to go. This result is not meant to be realistic - just practising my modeling. The skin is a pretty basic shader with some SSS thrown in. Only the third time Ive modeled a head, so pretty happy.

EDIT: Replaced original image with a more complete one, following Sean's comment below. Heads a bit bumpy - needs more work.
