Hello,
my name is Liliana, i have over ten years of experience as a designer, and i made this kind of projects before, i can send you some samples, if you want to.
In the maentime you can visit my Freelancer portfolio on my profile page, to see some of the vector illustrations and designs i made, in order to evaluate my work.
I use Illustrator and Photoshop for this kind of projects, i can combine the vector images with the mugs and other products, to show the finished products on the poster, like the attached samples.
I found this project really enjoyable and interesting, and i would like to create originals and clear posters, with all the products and designs.
I 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.
Best regards.
Lili.
