Well, Kryton looks nothing like the real person playing him so are your prints a likeness of the actor as he looks in real life or the character of Kryton as he appears on screen?
I'm not really bothered.
I like how this has become about copyright, when I can guarantee that these posters wouldn't care if the shoe was on the other foot. If it's clear direct copyright infringement, I'm against it.
When it's vague like this, it can go into the grey box it lives in. My models are sculpted by myself and also commissioned by myself. I technically own the copyright to my files... which have a likeness to TV show characters... sure.. probably wouldn't hold up in court. But it will never get that far.
Might start doing Micky Mouse prints In 2024 too...
So, I'll no longer be discussing Copyright in this thread.
