I love It !!!
You have a good understanding of the face and its arrangements! To improve, I think you should look more at noses, the shading on them and their shapes. Currently, it appears somewhat flat and lacks some form.
Thanks for the feedback. Yeah, I find noses hard. Tried again. Getting better? https://line-of-action.com/art/view/2380
Yes! The form is much more clearly defined. Keep it up and keep practising!
