I love Anthony's customs, though I would switch Pyramid Head and Janitor around. While Janitor was a great additional character (not in the games, it was a new one for the film) I don't think he should be on the front cover.
I reckon: Pyramid Head on the front (poster art), Dark Alessa on the back (when she finally meets Sharon at the end, the close up of her face as Sharon passes out), and a shot of Rose and Cybil when they're in the elevator during the Pyramid Head attack for inside art.
I've already got the DVD steel and tbh I'd settle for a G2 conversion of that. I love all the red
