RM Skill: Undisclosed
I've never played Eternal Darkness, but I did recognise Nayru from Zelda (because of the fairies, lol; it's been forever since I've played Zelda, so I hardly remember the lore).
Nice work on Zenjiro and Kojito, though I think their faces/facial structure appears too cartoon-ish to me. Maybe it's because I don't know who they are and that is the style? Was just noticing the structure of the face, for example on Zenjiro his chin is so far back by comparison to his nose and his eyes are kind of sunk in (or maybe they just appear that way because of their curved nature). Overall, it's amazing! And you should definitely keep working on these. ^^
