I have been doing some illustrations for a textbook company that makes English language textbooks for students in southeast Asia. The textbooks cover very basic concepts and the illustrations are supposed to explain the meaning of certain vocabulary.
The following are a few of these illustrations I have done over the course of the spring/summer:
animals that live on the farm
telling stories around a campfire
visiting the aquarium
visiting the zoo
These were all done very quickly, but still traditionally in graphite, watercolor, and ink!
