Okay ive had a couple of my friends ask me how i manage to do wavy hair on my characters for my mangas so heres a little tip for those who arealso having trouble with this kind of thing. what you wanna do is lightly sketch the persons hair as if it was straight then over the straight hair draw the wavy lines for your intended goal and erase the straight ones simple... ill post a pic or something so ya'll will understand better.
