I know we haven't seen PS yet but we saw the trailer and the music video so we know the animation it will have. I think Technicolor has developed very much. The character's hair in PC were all very unnatural while in PS they are a lot better. Also the colors used are much better. Also the face and clothes look way more natural. But Technicolor keeps on having quite a bit problem-They don't have a appropriate blonde hair color.
All the hair colors seem very good except the blonde ones. Kristyn has normal blonde hair only when she wears the pink tutu. In the beginning she has yellowish-golden hair, in the final performance they are quite strange and dark.

Barbie A Perfect Christmas has a very good animation. Barbie in The Pink Shoes I don't like as much at the moment, it's just ok.

THE HAIR.
And I said everything.

I say that the animation is as worse as PC. Even in the teaser trailer's Kristyn's face is much much much prettier than in the music video/2nd trailer/blooper. I was kinda hoping she will restore the glorious days of Mainframe animation, yet in a shot her face reminds me of a peacock's face.

For a while the animation was looking pretty bad, but this film showed that Barbie entertainment can bounce back with there animation.
