The technique I used, Duik in After Effects, seems to be one of the easiest way to do this, animate illustrations, without having to adapt the style. They were not meant to be animated at all, so it could be a bit tricky to adapt them.
What’s interesting is that those characters were… Well, illustrations. I’ve been very happy to work on Justine Cunha‘s wonderful illustrations recently, and I’m going to share my process with you.
