You can do this in any medium, in fact i developed this way of drawing lips when i was working in pencil.
I've been doing a lot of realism lately, that you haven't seen because i still have to finish it
, but i showed my friend
and she really liked the way i drew lips so i made this tutorial for her.
Up close they don't really look realistic but they do when you view them from far away
Sorry if i made spelling mistakes, i'm awful at typing and i didn't have spell-check.
Hopefully this is at least slightly useful to everyone.
This is just a guide to how i paint them quickly, make sure you edit it so it conforms to your style.
If you have any questions feel free to ask.
If there are any tutorials you want me to make ask me and i'll consider it.
