Hello,
my name is Liliana, i have 10 years of experience as a designer, and what i like most is to illustrate for kids, that's why i like this project.
Please, check my Freelancer portfolio to see some of the illustrations and cartoons i made, in order to evaluate my work. I can send you more samples, if you need it.
I use Illustrator for this kind of projects, i can deliver you the originals as vector format, and also saved as any other format you may need,
like JPG, or transparent PNG, for example.
I've read the description and saw the link, and i found this project really enjoyable and interesting. I would like to create originals, detailed and colorful illustrations and characters for your books.
I hope that we can work together, please, contact me if you have any questions, or if you want to see some more of my work.
Best regards.
Lili.
