Now, I have to wait 90 days for my next resubmition. Please give me some critique, as I cannot find why these pics would be rejected.
This are the 3 exact (unwatermarked) pictures I've uploaded:

reason for rejection:
At this time we regret to inform you that we did not feel the overall composition of your photography or subject matter is at the minimum level of standard for iStockphoto. Please take some time to review training materials, resources and articles provided through iStockphoto. The photographs provided in your application should be diverse in subject matter, technical ability and should be your best work. Think conceptual, creative and most important think Stock photography. Try to avoid the average eye level push the button perspective of a common subject. Try and impress us, we want to see how you stand out from the crowd.

We welcome you to return after the number of days specified and upload 3 fresh samples of your work and we will re-process your application.  Please note that you will not be able to upload new samples until this waiting period has passed.

Now, if you wanted in on any other agency I would help you.

But not here, Im in the process of deleting my port at that place.

I think you didn't take on board the advice you were given in previous threads. For the two isolations, your whites aren't white - they're gray-ish. In the picture of the model, it looks as if you focused on her ring, not her eyes. If her ring is the subject, the composition is all wrong. If she's the subject, then get her eyes in focus.

The cables are a bit underexposed, but not horrible, but from a composition point of view it's not really a background (can't use those dark areas) and it isn't close enough to be a macro shot. I'm guessing this would be accepted if you were already approved but just isn't good enough for an application.

The coffee beans in a glass mug - even if they were on a truly white background - just make no sense. I don't know of anyone who stores or uses coffee beans in this way (if it's a cultural thing, apologies, but stock deals with the obvious and I'm not getting this)
