gimmie one drawing i did and i'll tell you how I did the shading

"starstuck,young and deadly?" if so I use a light shade of grey (not to light,a middle,that softly lights it) and colour half the body and hair and then take a very light grey (almost white)and make an outline of the hair and body to make it lightened and then for the darker half I do almost the same get a (slightly darker)middle grey,use it to darken the other half grab a dark grey,almost black,and outline the outline of the hair and body

all of this is done with paintroller btw
