no worries. That is the only time I reject them is if they are going in the wrong folder. So if it gets rejected just know that is why and just resubmit it =]
All I can think off is that you put it in Featured by accident. Even though you were going to put it into WE Manipulations.
Not in this group but in another one I had picked out manipulations but somehow it got changed to featured.
Images get denied if they are put in wrong places, and since your work is very lovely and has all the copyrights on it, it is the only thing I can think off
