Shading tutorial, part 1

Part two is showing you how to shade with hair and clothes. If enough people think I should continue then I'll post part two.

I know there are plenty of bases (such as the bald head in this) in my work. Some people have been taking the bases without asking, changing them a little, and posting it as their own without crediting me. I dont want to sound selfish but I'm afraid that I now have to enforce this beacuse of people who are too lazy to do their own work. I know my drawings are basic and dont seem to have much more than just an outline but please, DONT STEAL FROM ME.
