These images are also from my tree book. Working with a theme you are able to develope so many ideas. You notice pictures in papers and magasines and your focus is on the theme, in this case trees, wherever you are. It is important to choose a subject that interests you and one that is not too broad or too narrow. You need to be able to source the subject without getting lost in the amount of information. Fortunately, it is easy to keep going going as one idea “pushes” you forward to the next.
