The face is lopsided. You can see this thanks to the double red line. It goes through the chin but not the middle of the forehead. The entire right side (our perspective) is higher. Especially the eye will trigger the “something is off” response. The shadow to both sides of the neck suggest light from the top/front, but then the nose would need appropriate shadow as well. The mouth sits too low on the face.

I recommend using the Loomis method to learn how to draw the shape of heads. You need to understand the mass you are drawing, not just single parts of the face. Right now, you are guessing shadows and placements based. Google Loomis, it’s a very popular resource for learning to draw faces and heads. Loomis also shows very cartoonish variants, which is more in line with what you are going for (rather than realism), which I think could help.
