In my opinion that shouldn’t be the landing page. If someone is going to the books’s webpage usually they want either to buy it, or to read about it. They almost certainly do not want to see a pretty animated introduction. So, put the book page first. Instant gratification is key nowadays. Then put a link saying something like “learn about characters” that goes to the animation. Extend the animation so you have one for each of the three people on the cover. Make it a branching thing, first the “loading” screen, make it give a menu with the 3 people, each being a link to an animation about that person.
