For a linguistic experiment which was conducted to elicit spoken language (image descriptions), I was commissioned by a research team of the Humboldt University of Berlin. They needed 40 illustrations: 10 sets of totally different images with 4 variations each. Here you can see 2 complete sets. From each of the other sets I only show you my favorite.
The project was a lot of fun because I also had to work strategically and to be as effective as possible while incorporating changes and minimizing redundancies in the workflow. This was completely new to me. Moreover, the given prompts have been a dream come true because I love to illustrate animals.
