Scorpion Shoulder Plates WIP

Scorpion's shoulder plates for his toga needed some reconstruction as well. Used a square-root paper to draw out a template and use it to cut out the pieces from felt and only on yellow part, apply 1 layer of gold acrylic paint for extra strength and sturdiness. The question is, should I also add in gray outlines on the black part, or is it optional? I wonder. o_o?
