Harley Quinn: Birds of Prey is battling it out in the box office with this week’s releases. Now, one of the concept artists behind the film showed off some of the alternate looks for Black Mask’s most defining accessory. Now, that look might not be the first way that fans see Ewan McGregor’s character in the film. But, comic fans know that the villainous alter ego is on the way at some point. The other versions of the mask are subtle changes. Some changes in the finish here, and some shaping and line work over here. Kyle Brown should be very proud of his work on the villain.
