Hello,
my name is Liliana, i have over ten years of experience as a designer, and what i like most is illustrate, that's why i like this project.
Please, check my Freelancer portfolio on my profile page, to see some of the illustrations i made, in order to evaluate my work. I can send you more samples, if you want to.
I use Illustrator for this kind of projects, i can deliver you the originals as vector format to print, and also saved as any other format you may need.
I found this project really enjoyable and interesting, and i would like to create originals, nice and professional illustrations that match with the style of the book.
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.
