Ever think location has something to do with it?
Admas is from Belgium?? I can't remember... Anyway he could send the sculptures via air mail or something, I don't think the distance is a big deal on this kind of job. The sculptor only has to do one sculpture and then Hot Toys can replicate it. (I think, I'm not sure abour the process).
More a case of retaining artistic freedom
You mean maybe he is an artist who only creates what he wants for personal pleasure? and not for money as a job?
