Hey, you should work on your fundamentals, i would advice to study and practice perspective religiosly (there are plenny of youtube tutorials con how to get better at this, i reccomend moderndayjames or scott robertson channel) , if you have the passion/time for this craft. Keep drawing!
Hi Jellyfish, try to be more loose with your lines, also the ribcage in most of these poses look kindda small, you should update longer poses too for better feedback, but I belive working on perspective will also help you, just draw cubes and try to connect them with the line of action to create poses, remember to give them form
