meow maybe try working on like anatomy and different poses end stuff and then like study peoples faces :D like you know that "face type theory" trend on tiktok? that kinda helped me fix my same face syndrome because the drawings in there show a nice variety of different face types! also when it comes to character designs (yours r so cute i love ur art style <3) I like to base the design sorta off their personality. Like if you have a childish outgoing character u can make them have big bright eyes. Or for a mysterious character you can make the facial features thinner.
