Alright, I'll bite. First of all, if you ever try and draw in a lined paper notebook again, I WILL murder you. Get yourself a sketchbook and some better pencils and improvement will come.
I think you're doing well proportion-wise but you have some issues with anatomy and depth. If I were you, I'd forget about trying to nail anatomy and proportion for now and focus on the basics. If you want to get a good grasp of the 3D form then it would be extremely helpful to draw basic shapes (including shading, so pencils with difference leads are an asset) until you nail the 3D form. If you're interested in drawing portraits then maybe getting some photos to draw form as a reference because there's no way you can accurately draw the human face as a beginner without a reference, be it from life, a photo, or anything.
You might find it helpful as well to draw the individual parts of the face (eyes, nose, ears, mouth, etc) separately, and for a couple of days really focus on nailing that part of the face. Then slowly piece it together (draw the nose and mouth together, then the nose and mouth and eyes, etc) until you have what is eventually a full portrait. Once you get a good idea of the form and shapes of the parts of the face, as well as how light works on it, then you will be able to qutie easily piece together a full portrait.
There, I'm helpful. >:|
