It's easy to fall into drawing the head first but starting out with another element can help with posing problems. Whenever I want to switch up my pose composing, I like to start with either of these four! There are a bunch more though and I feel your drawings follow whatever your start drawing first.
Drawing torsos first is a safe way of starting a drawing and I personally like starting with big shapes when composing that way I can figure out the size of the smaller elements!
