One of the best things about being an illustrator, besides the drawing, is how you encounter and get insight into a lot of events , phenomena and other things that other people are working with that you might otherwise never have heard of.
The big challenge is to visualize this new world you have discovered in an interesting and contextually good way.
Here and on my website you can see a little bit how I work. With pen on paper, processing digitally and eventually adding some color.
Lately I have started to work more with patterns.
