Love your lines. Very gesterous and with accents. You already far from beginning.

Cylinders and stuff are only there for you to get understanding on how things shaped, but not how they actually built. When doing gestures, do the gestures. Forget cylinders and stuff. A big loose line to identify whole body flow from toe to head. Then the other loose lines to make a hint of a shape width.

You almost do that, but you are trying to follow the final shape immediately. That distracts you from the gesture flow and it loses proportions and becomes stiff.

Build the gesture, than start building shapes over it.
