pretty acurate, the characters are spot on, as in, the parody was done just the right way as in it encompasses how they act in the show pretty acurately, but exagerated, of course.
I really like Steven Universe, but OH GOD, Steven can be super annoying, and sometimes the characters just let him get away and do absurdly stupid and irresponsible stuff, sometimes he screws everything up and in the end everyone laughs!
I dont know how they get along, if I had to deal with a stubborn brat like Steven I would probably hate him.
Anyway, great parody! Also the way you drew the characters is spot on, too!
