I found these great tutorial books at an online store. Lee Hammond, an amazing artist, has written books to help artists better their art. The first few chapters are devoted to the basics, materials, the basic shapes, shading, perspective and grids. Then the drawings become more difficult, buildings, clothing, toys, animals, people and statues.
She has books for not only drawing in pencil but also, colored pencil and painting in acrylics.
