what about collective creations, when more than one person creates the same artwork? this should be ok, right?
If the artwork is same which is created by a multiple person for example a Boat is designed by a person and another person also designed another boat and also another person designed another boat. Then there is no problem as all the designed will not be same their must have a difference. But if any one copied from another person then that will be questionable.
Yeah that's what I was also explaining above that you can use same things in your artwork but there's no possibility that the two artwork would be identical unless you try to copy someone's else artwork to present your entry.This is just a competition and try to be creative and submit whatever you have in mind and no need to be high profile artist to participate in these contest.
