Critique and advise for improving Portrait drawing

Hey

I got a loot of Feedback to my Sketchbook Uploads. Thank you all for that. It helped me a lot.  I tried to incorporate and improve accordingly. 

I would be very gratefull for Critique to the more detailed Portraits but also where you think I should invest more time. Idealy with advise for exercices or methodes.

Off course i will continue to Draw and get more practice and hopefully expirience.
