This was not a commission but something I done on my own time, based on a story I was and still am writing under the same name, there was some research into it, studying Ridley and seeing if he had "intelligence" (he does in the manga) while the metal bits grafted reflect the cyber upgrades he sometimes has. As this is a crossover into more Halo lore he is bulked up to be more fitting of a villain if adapted by western developer.
Likewise the chief is wielding a sword to symbolize his destiny so to speak, note as well the wording on that weapon is chozo writing I pulled from metroid prime. Finally the woman in the back is a halo foe called Ilsa zane (she is not samus!) but her role is part of Ridley's twisted sense of "humor" that relates to the title.
