Not the best costume design but nothing from that game is. The designers should’ve either went more comic or more movie with the forehead instead of those diamond shapes.
Sculpt wise it works. It’s T’Challa on a throne. Not but so much you need to do.
I’d say the lower part of the mask could be slimmed down a bit? The design looks like he’s got Sub Zero or Scorpion’s mask over top of his mask anyway. But it shouldn’t be as thick.
