Are you going off a real live person for reference? If yes post a picture or two so we can see if this person really looks like this, because atm this person doesn’t look real. A lot of his proportions are off. He looks good, but if you are really going for a believable and real person then people will be calling you out on those proportions unless you show some reference to back it up. At the moment the eyes are far to small, if he was squinting maybe i could understand the size but it doesnt look like he is squinting, just looks like the eyes are small. As stated befor the eyes are a little high, but also the ears are low, which together make them seem even further out of porportion. The eyes should be at the halfway mark from the bottom of the chin to the top of the head, and the eyes shouldnt be that high above the ears. Bring the eyes down a tad and the ear up a little and that will help a lot. Also his Head shouldn’t be narrowing as it gets to the top. When you look at someone straight on, their face will fit in a box, so the width of the jaw should be the width of the skull. lastly the nose seems a little too big but if you fix the eyes size I dont think it will be to big a issue. Hope this helps, looking forward to seeing more.
