Hi, For the website [login to view URL] i am looking for a nice caricature character which i can use as profile of the site and for further marketing activities. The profile character will be answering questions on the website. I have the following demands: - a real person - serious looking character (for example use glasses) but can look a little but funny.(not to serious) - adult - simple and clear - has to match with design of the website You can see an example of a character i like in the attachment. It can not be the same or a look a like!
