I think this looks like a very interesting project and I hope it gets made.

As for this preview, probably a bit more text/narration about who the main character IS would have been good. Anyone who doesn't know the history of what Afanasiy Nikitin did or what makes him interesting (which would be the vast majority of people in the West, not sure about within Russia) would find this video pretty confusing - "Why are there Oriental-looking people? Why is there a bizarre mishmash of Indian and Russian folk culture?". In the interview by Pyotr Akhlamov, Aleksey Olegovich does a very good job explaining what makes this man and his journey interesting. Perhaps a few of the key sentences could have been added to the beginning...
