Hello Nekorea!
These are very good and indicative of someone who is very comfortable with drawing figures! I would say by far 70, 72, and 73 are your strongest gesture drawings. My biggest recommendation would be blind contour drawing for your stiffness. Its difficult, but it has done wonders for everyone who has done it and really studied the purpose behind it!
I might even recommend using a pen or broad sharpie so that your strokes become more confident and purposeful. Try to do your gestures in a single stroke without taking your pencil off the paper. Try focusing on getting the whole figure down, even if its just a stick figure, before you really start leaning into the details of the body.
Otherwise these are very good for a several year long hiatus! Your longer drawings are definitely extremely strong and well done! I would be proud of them!
