A great pencil for artwork is one of the flat carpenter's pencils you can pick up at a building supply company or hardware store. Sharpen it with an exacto knife to a large flat lead, this way you can use it flat for shading and large areas, then turn it on its point to make your details and line drawings. Try children's crayons, you will remember those childhood days when you were so happy with a box of 68 colors, including Gold and Silver. Do a fashion sketch with a wax crayon or several in natural colors. You are your only critic at this point in time.
Colored pencils are wonderful.
As soon as you can, get yourself a decent sable brush and some India ink if you can find it, or you could use black liquid acrylic hobby paint thinned to the proper flowing consistency with water, just be sure to clean your brushes well if you use the acrylic. To wash your brush, put a little dishsoap in the palm of your hand, and scrub the bristles into your hand until the last trace of paint is gone, then rinse well, and shape the bristles back to their original shape and store handle side down in a glass or jar. So it is quite a new experience and new skill to learn.
