>>418983175 minute episodes basically means that each episode is more like a long commercial. Which Colorido more frequently does, they've never been a primary contractor on any TV anime because they don't have the resources for it and they know it.
>Director has never been a head directorThat's because Shingo Yamashita has been more involved in directing and storyboarding OP or ED sequences. A project like this doesn't need an experienced series director, because it isn't a full series. His storyboards are good, he can SB great action and character expression.
>Character designer has never been a character designerAgain, not a full project, it's a good opportunity to take on character design roles. This is the kind of thing Colorido and those affiliated with it do best.
>3D CGIAll anime use some amount of CG even if it's just for layouts and references.
