The question is how to create similar illustrations? Maybe a filter is used in a graphical editor or something else ... can someone tell me something?

Answer 1

Such illustrations are drawn by hand, the simplest thing is to find an artist who works in such a style and order illustrations from him. Often such illustrations are drawn from photographs. I would estimate such work at a couple of thousand rubles per illustration (contacts are in the profile, we can discuss), but in general the spread is very large, perhaps someone for 200-300 rubles. It will be taken, ad and freelance sites are known.
