i really like this pose! you definitely understand how the torso/hips are angled, but perhaps the reason why the twisting isnt caught is because it isn't exaggerated enough? i (probably) used a different reference than you + exaggerated the pose in my redlining, im personally a big fan of gesture, so even though my reference image wasn't nearly as dramatic making the spine curve more like an 'S' makes the drawing more fun in my opinion i thought a lot about this video from fourleafisland titled 'can you only draw a stick figure' when drawing these boxes. if you are looking for video resources, that may be fun to check out :D | Artwod Feedback
