To begin, let me just say that the costume is fantastic, very true to the original.
You will note that he appears to have long fingernails, perhaps a result of his treatment? There is no way that Barnabas Collins can be accepted by anyone looking like this. They'd all know he is a vampire. It's like Edward Scissorhands. We all knew he was different. Perhaps the lighting and after-effects will alter his appearance. As others have said, he must be walking out in the sunlight for the first time, otherwise he wouldn't need those shades and gloves. Reports have indicated that he had white make-up back in July. I am not entirely sure what the final product will be. I just can't imagine anyone accepting him as human or even relatively normal with that makeup job. Everything else about him (sans fingernails) is perfect, though.
