I'm just a student myself too, so take my critique with a grain of salt, please. As far as I know, the upper eyelid always protrudes further than the lower eyelid. I think this is something you might want to keep an eye on when drawing eyes. See the attached image. Also, I assume, you're currently practicing constructive drawing. The drawing has quite a lot of wrong angles (forehead) and missshapes (nostril), these mistakes often happen to me when constructing with 3D forms. I think you could benefit from practicing some flat mapping on the side, i.e. flatten the image to 2D in your mind, detach yourself from the subject and look for lines, angles and flat shapes, to develop your eye to notice these mistakes. I think you're doing fine. Keep on practicing.
