I had enormous fun sculpting Mr Punch on Don Lanning's excellent course a couple if years ago at Gorton Studios in Aylesbury.
I wanted him to have very exaggerated features, but with a realistic skin texture. I tried to capture the arrogant sneering character of him, and imagined him to be a ruddy nosed Victorian dirty old man type, probably sat in a gentlemen's club with a cigar and a brandy.
I hope you like him, but don't at the same time! :-)
