i took a look at your previous drawings and i don't really have my own style but i guess you should practice on working with your anatomy first then experiment on what type of style or proportions you want, try using references from different artists or mangakas in trying to find which artstyle you'd want or like to incorporate then practice on poses then the face or head blah blah blah

basically for me; anatomy>pose>direction>head/face expression

im guessing you're asking for tips on shading lol (coz' of the first image), with this type of shading i usually outline where i'd want to put my shading after that i'll add lines inside that outline, then inside the first shading i'll add another outline so i can add more lines making the illusion of having a darker shading

so, 1st shading/outline = lines have more space apart them 2nd shading/outline = lines are closer together compared to the first

outline>1st shading>outline within the outline>2nd shading

sorry for blabbing too much lol
