The character will also need a name. His surname will be " O' Shea " which will be the branding.
Target audience: General tourist and children
Ideas for the visual style: Not sure
Urls to draw inspiration from: Darby O Gill and the little people (film). Google images of Irish leprecauns
Where the design will be used: Branding and follow up soft toys etc.
