>>26424773TWEWY was one the style I was imagining for, but also the style used in Dissidia would work too, they are kinda similar. He would also have more freedom then he normally does, like when he did Lulu's dress
Kazuya would be amazing for the reasons you said but also for the straight up expressions his characters make. It would be a great model.
Araki...Actually Araki might be fine, he's a professional with working in memerable charcter design and with companies. Like while it might be over-designed, it'll probably not be as bad as you are imagining and fit right next to roberu
