I did this illustration for a pitch for some black and white work, I liked it enough to colour up.
I hope it's obvious that it's Fagin from Charles Dickens' Oliver Twist.
I tried to make him look shifty and vaguely dirty. I also tried desperately to avoid him looking like Alec Guiness or Ron Moody, it's ended up more Wilfred Bramble from Steptoe and Son than anything else I think.
I had the words "You've got to pick a pocket or two..." rattling around my head the whole time I was doing it, sorry if you now have that in your head too!
