youre good at drawing male bodies, best advice i can give is to experiment with other shapes, since you seem to be more experienced in drawing square-shaped bodies.
For triangles you can use the hourglass body and for circles what i mentioned with beans
Its more noticeable on cartoonier artstyles but shape language is used in more realistic shit too and it helps with different body types, just experiment a lot, try doing the opposite of what you usually do, and maybe youll find something to implement in your art commonly to give it more variety.
