How do people just draw poses without reference
Ok so, for context im a digital artist only and ive been drawing for about 11 years. My art has sort of become stagnant for the past 3 years, since ive basically been drawing every 1 or 2 months or so.
But anyways, there's this certain style of work that ive really been liking where its a digital sketchpage basically. And it contains characters in poses that are either complex or simple. I think they're really cool and usually theyre telling a story or based off a scenario etc.
I really want to try that too, but ive realised that i really struggle to draw without a reference. Even if its something as basic as a front view up to like the shoulders. So my question is how do people go about drawing sketch pages like those, like the pose and expressions and how can i be do that myself?
Also not sure if that tag is right but oh well.
