Went back to my ribs to fix them all after watching this and Proko's examples, guess I've been doing them a bit longer than what they actually are haha, any feedback is greatly appreciated

Hello! Here are my attempts, I feel I struggled the most with the perspective, specially with the back of the ribcage like #9, any feedback is appreciated!

Hey! 1-3 is from reference and 4-6 are from imagination, would appreciate any critique :)

Decided to try and cover many of the angles to make sure I understood the shape better, my lines got a little cleaner halfway through because I started simplifying it as cubes and then did the actual pelvis shape, I struggled mostly with the upper ones I guess because the circle shape

Here are my last attempts of each picture, at the beginning I found myself struggling to do the curve of the spine without having to trace it, by the end I felt a little more confident with the way I did the spine. Also any feedback is greatly appreciated!

Hi everyone! Here's my first attempt and the last one after checking the answers of the examples, I think my main struggle was that I'm doing the spine too thin and figuring out the right angle and proportion of the sacrum. Any feedback is greatly appreciated.

Hi, here are some of my attempts at this, I decided to do these exercises in paper since I'm more used to digital so I really struggled to keep my lines clean, guess that's something I need to pratice

Just like with the muscles I have already done this exercise like a year ago, so my notes and the pdf helped me identify easier the joints and shapes, but I guess I still have to practice perspective

This is actually my third attempt, I started this course a long time ago but life got busy so I couldn't go that far into it, but back then I made a completely blind version, then I corrected my own mistakes with the help of the other videos and now this time was with the help of my notes from back then and a bunch of muscles images
