Can someone clarify what is meant by original please? Surely any pic of a Transformer is not original as it'd be copyright Hasbro.
For instance, I own a t-shirt that looks like...

which, as you can see, is a Terminator head realllllllly up close. I personally think that a t-shirt in the same style but with Optimus' movie-style head (and in particular his blue eyes) would look absolutely fantastic.
But does that count as original? I can screen grab the Transformers website and crop it to get the right size Optimus head but I don't know if that's against the rules or not the point of the competition.
Any advice would be appreciated!
