I agree with what people have been telling you but I think you can pace yourself in practicing those things > < It'll feel more natural to you in due time. As long as you don't rush too much as compared to actually feeling like you are progressing.
I really love how you drew the Keymaster! Nice poses :> Honestly, I like how you draw the legs and eyes.
Good luck with your journey in art and I look forward to more of your art whenever you feel like posting ' v ' b
