How should Nigel look in cartoon form?

I don't think he should look vastly different to the way I do I suppose. I think that there should be a sort of gauntness about him, which I obviously would have to work on, but I think he would have a sense of being slightly dissipated and drawn.

At the same time, he rather enjoys that look of, 'I could die at any moment' - he's got that kind of look about him, slightly melancholic but sardonic at the same time. Obviously I don't think shaven heads were the norm in early 19th century England, but if he had short hair that would be fine too.
