Those are looking a bit better! Good job!
Your full drawing looks good! And there is a lot of good line confidence there!
Thank you, I have practiced a lot of environmental but neglected my gestures. It's like skipping leg day in the closest expression. lol. Also need a drawing screen tablet eventually. 
Everyone has their favorite!
Yup the non-screen one is a pain at the beginning - I was drawing circles, lines etc for ages to get used to it(with a variable obsession with the undo button 
) But it gets better, and also the skill transfers really well to a screen one so your time is not wasted.
These gestures keep getting better and the line quality has gone up a ton too! Keep up the good work !
I don't know how to perform the 4th line.
made an attempt at a portrait drawing
