Base Drawing

I usually don't do a base drawing, as my process for digital sketching involves a lot of mark making and revision. Because digital techniques are so forgiving, I can keep the lines I want and delete the ones I don't with no overworking of the substrate (unlike when you do stuff on paper, for example). So starting with a base isn't something I normally do, and after doing this trial, not something I intend to do in future. But it as a good trial.
