HELP! How to stop drawing giant heads!?

[SHIRUBA]

It definitely makes sense starting with the larger shapes first and then slowly refining with the smaller ones. I guess I'm still to eager to draw everything perfectly from the start. Really need to internalize that it takes times and a lot of practice until you reach a point when even your quick sketches are anatomically correct.

Just gotta put my head down and study! Thanks darktiste!!
