The main drawback of the cartoon as a whole is its pattern: the protagonist, according to the laws of the genre, has a kind heart; an antagonist because evil; the one character who lost his family because of the antagonist, and wants to settle accounts with him once and for all. The plot itself is a bit like the Soviet cartoon "Seraya sheyka". Another drawback is the repeated demonstration of the termin of "death", especially in the children's cartoon.
I myself am confused by the graphics, it sometimes looks crooked and sloppy, and weak, unlike other similar cartoons about birds.
One character a ptarmigan Giron looks like a yeti-bird and looks as a permanently drunk middle-aged uncle.
In general, I recommend this cartoon to regret and forgive.
