Maybe a black metal or obsidian (black and glossy) base instead of the bone. Expand the replaced piece to be longer with the two side pieces being more vertical at the front. This is give it a more crown shape. Instead of the glowing cracks, give it small lines of hive runes running up and down various parts. These are relatively sparse and small. They glow just like the cracks. The standard helmet version is a hit sleeker drawing more emphasis to the front. I’ve been wanting something for it for ages and love the whole crown aesthetic of Crown of Tempests and Nezarec’s Sin. Add in a more demonic, hive-y vibe and you’re Golden.
