to see some of the illustrations and icons i made for children's books and learning games, in order to evaluate my work.
I can send you more samples similars to the ones you attached, if you want to.
I use Adobe Illustrator for this kind of projects, i can deliver you the icons as vector format ready to print, and also saved as any other format you may need, like JPG or PNG for example.
I found this project really enjoyable and interesting, and i would like to create 60 originals, simple and fun icons to represent each subject, vissually appealing for kids, like the attached samples.
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, or a mockup for this project.
Best,
Lili
