I think the structure on these torsos are really nice and most of them look really decent I guess if you want more expression in your forms try to imagine each section of the body more as basic shapes so that you can be more expressive in terms of foreshortening and having bolder moves with each decision, A good book to help find these simple shapes is George Bridgman's Drawing from Life, Watts Atelier has a book about Bridgman but you can just look at Bridgman directly if you want and also last bit which I'm personally kinda confused about and you don't really have to listen to but should the scapula be a bit larger in terms of proportion or am I just imagining things?
