Thank you so much!
My blanket statement for any progress in drawing is practice, practice, practice. I know it’s said a lot but there’s a reason it’s said a lot. It really helps. Specifically for facial diversity I recommend finding a basic method for drawing faces that works for you, gather diverse references—and you’ll have to actively seek them out because a google image search for “human face” is very telling (hint it’s nearly all white people and there’s a white person in special effects makeup before search returns on poc soooo that’s the general hell world we’re dealing with when looking through media for references) I’ll show you my face drawing process and point out what I look at to make different faces
Okay so we’ve got the basic layout to start, and next I go in and add super basic shapes to specify the area the features will take up. I don’t worry about them looking a certain way at this point, I just want to designate the space.
So the next step might look like a leap has been taken, but really I’ve just played around with lines to define the features. It really helps to learn the names of individual facial features so you know what to experiment with in the first place. For example, when I look at the nose I look at what the root looks like in relation to the bridge of the nose and to the eye sockets on either side, and how the collumela is crossed by both the tip of the nose and the philtrum and the nostrils on either side.
Study how different features manifest on different people. Look at the eyelids, cheek bones, jaw line, lips, brow bones. If you’re looking at different tutorials be mindful of the language used. You’ll find a lot of education materials describe features with white features as the default and all others as compared to them (i.e. “wider nose” “fuller lips” etc.) so when you do, give it the stink eye and remember it’s bullshit. So practice, practice, practice, and seek out facial features we don’t usually get to see reflected back to us.
