I like the perspective.

Trying to get zero-g reference is challenging, unsurprisingly This one is from a model ref website which had some shots of a model hanging from a trapeze. I've also collected a folder of underwater shots which are about as close to zero-g as you can otherwise get.

Of course, these photos are purely for reference - it still comes down to knowledge of anatomy, drawing, etc. That's where all my years of life drawing come into it.
