Here is the same scene - a cave mouth in the middle of a forest - drawn with three different thicknesses of line because I wanted to see how they would look. The scene is from my imagination but it is amazing to me how the details - the exact arrangement of ferns and bushes - ends up so different from one to the next. This is partly due to it being easier to block things in with a thicker marker and easier to get more detail with a thinner one. But it also goes to show that the imagination is often far from static, even if the basic concept remains the same.
