I know MGM has pointed out that Mattel has used shading on other capes, but the shading was an all-over effect, not just one spot, and the colors used blended better with the base color.
The color of Snake-face's snakes don't bother me. The answer to the armor does. The palace guard/BA was thickened to accommodate the switch-out plates, but only in the front, not the entire armor piece. Why is something done two years ago such a challenge now?
I'm not an artist, I'm not a toy designer, but some of these design choices are just... odd.
