Hi! I'm new here and I hope I didn't post this wrong...Anyways, I was wondering if any of you guys had tips for shading and hair shine. I am not all that new to being an artist, but I could sure use some work! I have no idea how to shade correctly. I have a vague idea of how to correctly do hair shines. I would really appreciate it if some of you would tell me some tips!
