i don't like how it looks when i sketch directly /over/ my thumbnail sketches (not proportionate, too sloppy) but when i use it as a pose reference for a secondary sketch, i feel like the end result is way less expressive :T i actually love thumbnailing, i find it fun- it's just frustrating trying to translate those drawn on paper thumbails into the correct page dimensions, since i often just have to overhaul the paneling composition i originally made in the secondary sketching process.
i also hate how many layers i get . . . i have a very simplified style and process and yet somehow, it's like i. blink and there's 40+ layers, all of which i forgot to name. smh
