Hello,
my name is Liliana, i have over ten years of experience as a designer, and what i like most is to illustrate, that's why i like this project.
Please, visit my Freelancer portfolio https://www.freelancer.com/u/webpolis.html
to see some of the food illustrations i made, in order to evaluate my work.
I can send you more food illustrations samples i made for stickers, if you want to.
I use Adobe Illustrator for this kind of projects, i can deliver you the illustrations as vector format to print, and also saved as PSD as you requested.
I found this project really enjoyable and interesting, and i would like to create originals, simple and fun all kinds of food illustrations.
Hope we can work together, please, contact me if you want to talk about the project, or if you want to see some more samples of my work.
Best regards.
Lili.
