for gesture, try going more stylistic if you want to, push yourself into exaggeration. for anatomy, try starting to use soft and hard shadows. and basic shapes, try including them more often, but i love your work with line weight!
(unrelated but god i feel like i keep one telling abt shadows, there rlly important)
maybe try working on shadows and highlights nex, i think that would be good if you wanna render more things but idk man, you do you
