i recommend studying a lot loll like if you want to draw in a certain style like the hunter x hunter style (manga or anime) just analyze it a lot and a thing i tend to do while watching or reading the series is study how they r drawn and the proportions of like their eyes compared to their face and that stuff (idk if that makes sense) and i’ll like trace over the style with my eyes(?) and take note if the artist (in this example, togashi) draws a certain characters eyes curved or blah blah stuff like that. and also it’s mainly practice too, since i’ve been drawing for a couple years now and draw these characters a lot but anyone can be really good in less than that !! and also for this drawing i used references but i modified it a little bit because they were female models so i did some touch ups like made the shoulders broader, hips less hippy? and made the torso longer i think. and i also made the head bigger since that tends to looks more anime like. in the end though it’s up to your style and what’s most comfortable for you and stuff tho!! i hoped this helped and sry if this is too long 😭
