We're looking to add 2 new characters to our collection. We need both a male and female. Please see the pictures attached for existing characters. The new characters must be joyful, colourful, fun and attractive to mums and their kids.
Those products are traditional lunch boxes from Japan. We import from Japan but sell to Europe and North America.
Characters do NOT have to be drawn from the Japanese culture.
For example, you could go with animals looking like a human being. Or western-style characters. Design freely, be inspired, you have "Carte blanche".
In terms of constraints, please limit yourself to 3-4 colours. No fancy gradients or shadows, solid colours and thick lines. You can apply a different background to the head, face and body. No illustration on the back.
The pictures attached present existing products so please do not replicate. We're looking for something unique not follow-ups.
