Hello,
my name is Liliana, i have 10 years of experience as a designer, and what i like most is to illustrate, that's why i like this project.
Please, check my Freelancer portfolio to see some of the illustrations and cartoon characters i made, in order to evaluate my work.
I can send you more samples of mascot characters, 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 found this project really enjoyable and interesting, and i would like to create originals, fun, and eye catching ninja characters to represent each one of your company services.
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.
