Hi people! I hope they are well. Here I share some studies of value in portraits that I have been doing the last week. I'm happy with the results but I would like to improve the brushstroke, it feels a bit stiff and smug. But hey, you have to keep practicing and studying .. what do you think? How do you see it?

Hi, I finished Proko's anatomy course and am currently studying Watts on Bridgman book. Below is a drawing using photo reference from his book. I mimicked his design for shadow shape but also try to create my own. Not sure if I can upload the photo from his book so didn't provide the reference photo here. Can anyone please provide critique on this drawing and where I can improve? Thank you!
