Decide what kind of tools you want to use. In this tutorial I used a B, 3B, and 8B pencil to draw. I recommend using more than one grade to get better depths for a more realistic look. I used these to draw on drawing paper (I recommend to buy paper that is especially for drawing, it doesn't have to be pricy). I also used a pencil sharpener, tissues(to blend) and an eraser(in shape of a pen).
