I think the overall image looks great, the proportions are good. you are correct in that eyes are a little uneven, the ears are a little high, but the fact you already picked that out means you know what to look for. my suggestion would be to try a different angle, I have found front on faces always look strange no matter what, so what I would do is draw more faces try and get faster without loosing quality, focus on the parts you mentioned in each drawing understand their position on the face. and use reference, if a practice drawing doesn't look right, don't be afraid start again, but do something actively different so you can more easily see the difference from the first to second. have fun and I hope this helps | Artwod Feedback
