You need to practice yours simple forms. Thinking in 3D. As an example the eyes that are drew like an emoji, you have to think that they are a sphere and the eyelids are wrapping them. Also practice more the fundamentals.
simple forms help for sure. though idk if the chin is really the eyes thing, to me the jaw line just sits too low so the face gets long. maybe shorten from the mouth down a bit and keep the chin as a small rounded wedge so it doesnt poke out
