Many people stress out over developing an art style. Some try to draw anime, comic book style heroes, but it’s all a trap. An art style is 4 walls that bind your creativity.
Why not just draw? The more you draw, the more you will improve. If you like anime, honor it, but don’t stress out over creating a likeness. Do you want to draw comic books? You don’t have to draw like Todd Mcfarlane.
Don’t develop a style. Work on perfecting your craft.
