/ic/ - Artwork/Critique

WARNING: shitty english ahead.
The more i try to do gesture drawing the more i think i got some wrong concepts from my readings and i find it hard to get rids of them in practice, i know the only way to get better is practicing, but i feel like i'm losing my time with an unproductive application of foundamentals. I Hope you can help me to undertsand if these statements i tried to apply on these shitty 30 secs poses from reference are right:
-the head with an oval, every limbs with a C or S courve, and the torso with two oval shapes.
-The goal is to put togheter these shapes in a pleasant manner.
-You don't need to know shit about anatomy to do gesture
-The rytm thing is not part of basic figure drawing, you implement it with anatomy.

I found them all wrong, i don't know what to believe in anymore :|
