to see some of the illustrations i made for children's books and learning games, in order to evaluate my work.
I can send you more samples, if you want to.
I use Adobe Illustrator for this kind of projects, i can deliver you the illustrations as vector format, and also saved as any other format you may need for web like PNG or JPG, for example.
I found this project really enjoyable and interesting, and i would like to create originals, simple and fun designs for the activity sheets.
Hope we can work together, please, contact me if you want to talk about the project, or if you want to see some more of my work.
Best,
Lili.
