Thank you for the great replies chaps

I have done some more research and think for now in terms of new directions to work on, I will actually focus on creating a combination character utilising Manga and 'hip hop' style cartoon influences.

Cartoons created always have a flavour of ones own, but I can't afford to ignore trends...especially if the client is using a 'trend' related phrase when searching for their cartoonist. So as you say, there will be influences but always something a little 'different'...however subtle.

It's amazing how many variations on a theme there actually are in this industry. :)
