If you're talking about the Mewtwo's artist, you bet we've seen Shin Nagasawa before! Some of my favourite illustrations he's done are Naganadel and Giratina from Lost Thunder and the Dusk Mane/Dawn Wings Necrozma Tin Promos. A full list of his illustrations can be found here.This render looks really nice, have we seen this artist before? I think getting away from 5ban Graphics is definitely a step in the right directtion aesthetics wise.
