Except that it’s not perfect or realistic. The movement is wrong, the light is wrong, the figure is not weighted properly (her butt sits on the chair like it’s a hard malleable shell), the skin tones are cartoonish. Light produces various tones as it bounces off of objects in space, and as well as it recedes from the light source.
A brown object next to a blue one will see these tones produced in the reflected light. You see none of that here. Perhaps it annoys me I am a classically trained artist… I have a very calibrated eye for first principles in chiaroscuro, animation and the effect of weight on mass compared to the average Joe.
This is a nice video, but it’s not any sort of indicator about the state of CGI. I have seen much much better.
