Hey I looked through all your stuff and great work so far! I'd just like to recommend you spend more time sketching out your portrait studies before worrying about any sort of value. If you look at your earlier practice of the head, ears, nose, lips and eyes you can see that you have a good basic understanding of their construction. I feel like your recent studies however don't reflect that. Slow down and map everything out just like you practiced. Do several pages without even worrying about any sort of value. Once you're more comfortable with it you can start to render them. Hope this helps. Keep it up!
