I've had several artists ask for my permission to use my stock as reference for this contest, which I have given. (thank you for asking, I appreciate the communication)
However, I went over to browse the official rules of the contest:
- may NOT be recognizable as the actor Angelina Jolie or any other recognizable actor;
- must be the Entrant's original work made for the Contest and may not use stock materials from others although licensed brushes and textures are acceptable as well as original assets from the Entrant's own work;
- may reference but not actually duplicate visual materials provided in the Asset Pack.
What this means is that any art using my stock would be automatically disqualified for entry due to contest rules.
I would hate to see hard hours of work get wasted, so I would suggest not using my stock as reference for this contest.
I would assume the reason is of course the legal ownership of likenesses. If my face was entered in the contest, the company would then have to legally compensate me for display of my likeness.
I don't know what level of reference would be allowed (I.E. just an arm holding a bow) or if not recognisable reference is allowed. I would err on the side of caution to avoid disqualification.
