Okay i'm not a fan of this huge skull, but if you want to keep it, why not overact.:D I can see this ship as a Cruiser or even a small Battleship. Place a Hangar into the Mouth frame of the Skull and 2 Turrets within the eyes, so, the gunbarrels are remaining not visible, but the eyes are shooting later.
If it will stay as a GB, place two red glowing Running Lights within the Eyes and a Forward Gun into the Mouth.
