Besides the fact voice actor 1 is annoying to listen to; voice actor 2 is honestly pretty good to listen but where is the jokes? Jokes have set up, twist and punch line. This literally just sounds like American politics on Twitter with the two Russians arguing against one another.
"He is orange" and "Joe Biden is great president" ok, but where is the joke?
"He go into a coffin and wake up a zombie" ok but where is the joke, you two aren't playing off of each other.
Humor works when two people play off each other; you two aren't playing all that different of characters, in order for humor, jokes to work you need two people to be playing off of each other if you want to do this kind of humor.
Let me use an example, not a great example mind you but an example to get the point across.
Russian one: "Joe Biden has been shown to be sleeping at important meetings and the media focused on his favorite flavor of ice cream; he has failed to do any effective policy to help the average American."
Russian two: "He not orange like Trump, he's a great leader! He's been an outstanding leader for the rest of the world!"
Russian one: "Good leader? He left military weapons and vehicles overseas, what do you mean good leader?"
Russian two: "I never said he was good for America; now help me hot wire this tank."
Yeah my joke isn't funny but it's meant to get the point across; back and forth should be going between the two, the two should be playing off of each other; acting different from one another.
For the love of god; avoid the Teen Titans Go style of writing of; "look at this; we wrote two characters to be the same people with no personality differences!"
