Nicely done this is looking better! Nothing jumps out to me so just keep practicing! You're doing great.

Wow really fun and difficult facial expression with the mouth open. It's great to see how hard you're working on these portrait studies. It's hard to say without seeing the reference but from the side view the chin might be a little bit farther back (closer to the neck) so I might double check the side profile if you have a reference of that. Keep it up!

wow really fun! this one looks like there needs to be more clay in the back of the head so I might recheck the side view of your reference. The back of the head has a lot of clay especially in children.

Nicely done! great little study.

Great job doing so many of these little portrait studies! That's how to get better so keep it up.

Looking good from the front but the side view looks like it might need some adjustments. I would try to get more references from the side and double check the outline from the side view. Keep it up!
