hmm im not sure how to go about this so sorry if it seems all over the place
1. unfortunately the only way to get better at anatomy is to study it (which i know is very tedious) but i recommend simplifying poses/bodies into shapes. SHAPES ARE VERY IMPORTANT
2. if you arent-
try my own style.
5. i use adobe flash cs4! and for clip studio, i keep forgetting to record timelapses for my drawing processes but if youd like u can always reach out and ill try to record more drawing processes to show you,
