hey, I noticed something on your ribcage diagram, the reason why you're struggling is because you don't simplify. Try to find corners, even in curved surfaces, they always have peaks. Find those and turn them into corner landmarks. Boxify. More corners = more structure
Also, it seems like you're just duplicating the left side ribcages and flipping / mirroring them to create the right side ribcages. Don't do that, you'll need all the practice you can get, so just try drawing all of them from scratch.
Here are some notes:
BE CAREFUL AT THOSE AXES AND MIDPOINTS - they're very important to placing stuff like sternum and spine.
Of course, ribcages come in all sizes and shapes, some are even close to the box I'm starting with. It's important to gather some ref and do variations, not just stick to one shape. That's the beauty of anatomy, it varies so much that once you get the main idea, you can't really go wrong and you can play with the shapes all you want.
