a couple things:
his left eye is right next to his ear. in fact, I think he's looking at his ear right now.
actually that reminds me, generally in a face the ears are not that low. relative to the rest of the face, the tops of the ears generally align with the eyebrows or the tops of the eyes or something, I forget which. either way, though, in this picture his ear is right on his jaw. or maybe I just have my perspective wrong.
the nose is looking strange. it's mighty upturned, and I really don't see a reason to have left that one portion without an outline.
that line where the neck and torso meet is weird. I don't think there's a line there with people.
also why are they all wearing black lipstick on their upper lip??? for the first guy I can see it as creative shading but on the second it doesn't look natural.

avoid using anime if you're just beginning art. most anime is
packed with bad habits that you're better off not learning as your first style.
