They look amazig here! As if they were alive, but nor entirely human, their eyes are alien and they smirk in sch a devious way... They could be as well four main antagonists from some regular life action sci-fi movie, those that instill fear in the viewer and abduct people for mysterious reasons but still wear fashionable suits and pretend to maintain a company. Except Gamagori. He is just a guy here.
Nice though I would have preferred different facial expressions on Inumuta, Jakuzure and maybe Sanageyama. IMO their somewhat blank expressions kill the epic aura the drawings give them. Regardless, still very well drawn.
