This film is actually quite similar to Lafertovskaya Fig-tree (Лафертовская маковница).

Yes, I can see the stylistic similarity. Though the proper translation of "Лафертовская маковница" is "The Lafertovo Poppycake Seller"

This film is in Belarusian, so I tried everything but couldn't translate it. As for its title, I used Eus's plan.

Eus got that translation from Google Translate, but it's wrong. Try to search for both in quotes, and you'll see that the "poppycake seller" title is the one used by actual human translators.

It's in Russian, actually. I just checked. I starts with "Я хотела бы сходить за сокровищами… Не бежать от своего детства, а идти ему навстречу; любить и видеть то, что нельзя тронуть рукой: лес, воздух, тишину, небо, луну, время". (by the way, if you do a Google search for that, you will find the academic article "ЗВУКОВОЕ РЕШЕНИЕ АНИМАЦИОННОГО ФИЛЬМА В КИНЕМАТОГРАФЕ БЕЛАРУСИ", which talks about the film).
To be honest, I hope that a better scan of that film turns up. With the existing VHS scans, I find it hard to tell what's going on too often, given the detailed art style.
