Being happy about your study is the best thing you can get from your study, no matter how bad the quality is compared to others.
Gesture wise, looks noice so far. Recommend to try to make the gesture more expressive (e.g. push the line of action further or push the chest up more).
For fast face drawing, I recommend to not do shading but rather focus on basic head construction and facial placement and work from there. Eventually, once you confident then you can do shading in your fast face drawing.
But yeah, keep it up! Looks all good so far.
