/ic/ - Artwork/Critique

i'm study anime girl proportions from my favorite artists (such as Hamada Yoshikazu), do you think i am doing it the right way?

everytime i try to draw a body on my own, it is like i forget everything and the result is unappealing so i'm in a "fuck it, i'm just gonna grind" mentality until this is drilled in my head. that is why i am doing this method.
