I’m gonna sound like any other artist, but seriously, ref is kEY. Try studying it,(trace over it if you have to but please don’t post that) just do whatever to understand it. When you think you’ve got a hang of it, you can try sketching it without reference. (if it turns out disappointing than you can always go back)
If it’s a more dynamic pose, try loosening lines and strokes, make them curved and don’t add sharp edges.
it goes for stiller poses too:
but yeah, that’s all I got 😀 Please don’t cry. You’ll improve if you put your heart into it
