Andy, yea thats the new one. Basically, most of the "big" colored pencils shows aren't allowing work if you have had aided instructions from a teacher or other artist. Meaning if someone was coaching you or telling you an area that needed to be fixed, then it was aided and you can't use it as they gave suggestions and helped with it. Its a new thing they started and there was a big controversy on Wetcanvas a while back ago by it.
They are also saying that if work has been "published" meaning if it has been posted or comes from a reference on the internet that it is unaccepted too, though I do not know if it has gone through or not. The reason why they don't want it posted on the internet is so that a picture can not be claimed or copied by another artist and another artist can't help and give suggestive remarks to where you go and do what they suggested.
They are basically wanting it to be all your own work and if you use references they have to be from your camera with proof that it is all yours.
