Yo as an artist, try to understand when your proportions are wrong, IRL your hair sits on your head and at most adds a couple inches in volume, Gojo's hair is a lil poofy but try to understand that that his hair shouldn't just be a big ball. Also know that there is a space between the nose and the mouth. And the nostrils aren't just places willy nilly. As well as your shading. The shadows are supposed to be showing where the light is coming from, so if its coming from the right, shadows are gonna be in the left, but on yours its on both sides. And a BIG mistake your marking are those scratchy and hard to read lines, please make an effort to make clean strokes instead.
