People talking about differences in skin color & neck length should keep in mind that preproduction art does not necessarily match final designs. What a character looks like changes many times as they make a movie.
Yup. But something about the blue face strikes me as more expressive, which makes me think it's the face using Lupita's mocap performance.
Though admittedly it's hard to see just how expressive the orange one might be. The blue one seems more interesting to me in any case.
