We had David Revoy over to our place last weekend for the Krita sprint (https://krita.org/en/item/new-builds-to-test-krita-sprint-to...) and he was very enthusiastic about this project, saying that Nikolai was really good at drawing. He loved the trailer! The campaign definitely is blessed by David.
The campaign is also endorsed by Konstantin Dmitriev, the person behind the Morevna project who gave Synfig a new lease of life.
