Rose using stippling

In this exercise, the aim was to draw using just a black pen, but to create tone and shade using stippling.

I have to admit I wasn't quite sure about the stippling technique, and was initially unhappy with the effect - the dots looked a bit odd and just like a lot of dots. But then I tried to doing the dots rather more quickly, and found it easier to create the types of effects I was looking for, getting a denser concentration of dots.

However, I still resorted to hatching in some parts of the picture where I was looking for a lighter shade.
