Practise building up dark, medium and light tones using pencils and hatching and cross hatching, on a single object, with soft and medium pencils.
The bouquet looked like a single entity to me, but I’m not sure it qualifies as a single object. I may have to try this again.
The exercise says to use a variety of soft pencils on smooth paper and the example given is in colour so I have used coloured pencils. Also it is not clear whether two drawings are required at all. Perhaps we are given greater freedom to interpret the instructions.
We are asked to make a variety of marks so I chose three rock amalgams with different surfaces: fossil coral, amethyst and lepidolite.
