that's why we have sketch step in art!
also with big project like animation or poem i think about process as "fish from skeleton"
i do "fish head" with the idea and "what i am trying to say"
that's why my film "monster with red fangs" has reimagining of vampire myth - the "fish head" is antiracism message, and main heroes - black vampires, so audience should be at their side. But original vampire myth is "Vampire is a monster", which i played with. Entire film in the end is thought about "real monster is not who people usually clame so", and actual monsters there are Hunters
all is from "headfish" - "what exactly i want to say by my project", "what is main idea and theme"
after "headfish" it goes further - but still bones.
in my poem "and then the rabbit saw the sun", about my immigration expirience, i've made "skeleton" of chapters and what they should tell to audience.
it even end up in final poem - first chapter, in final poetic form, is asking questions which later chapters are giving answers
and then goes meaty layers - sketches, concept art/refs of characters, storyboards, raw version, semi-final version, final version Of Parts - then parts together
in my game "my rose will be my grave" (datesim) i made mechanics with test graphic and then started to add semi-final version of characters sprites, then - editing it to one style making it final versions
so, artists writers musicians , don't expect the magic button of "make a thing" - art is theatre with Most of things happening behind the curtains
