look up how to draw with primatives. proko on youtube is a good source.
do some random dumb shit. when you get to hyperfocused on somthing you hit walls. somtimes you find pathways around those wals by doing diffrent things. try cartooning. draw a dancing taco, it will help you loosen up and gain prespective. also, stop giving a shit about other peoples opinions unless it is actualy benaficial to you.
