The sketch here has been formed using lots of loose lines which together create an illusion of detail. It was drawn in a north-facing conservatory and the neutral light source gave very soft shadows making the subject rather tonally flat.
To keep my drawing representative of this flat light I used smooth paper and a fine propelling pencil. This created lines grey lines of equal thickness. With such a thin regular line I had to take extra care not to allow the sketch become too tight.
Still life's are so easy to set up and can teach you a lot a about lighting and shading. Try using to use a single source of light to help create strong stationery shadows.
The best thing is though, apart from the flowers or fruit fading the lighting is under your control and not natures!
