That's what i mean, no photo's to pin down a likeness makes this sort of thing hard, as he's not as blatently obvious as say Darth Maul, or Ozzie Osbourne , Elvis etc, so folks not in the loop would either have to have a note by him explaining the story behind him, which may not be read as he's not immediately recogniseable..
So going off at a tangent possibly, he'd have to be as recogniseable as say the little fella who is the character logo for the fighting Irish team, bow legs n'all as influence to make people look closer, (as they'd vaguely recognise his form initially)???
I guess i'm saying incorporate a well known shape / character as your basis for a relatively unknown one.
Generally it's celts & Halloweeners who'd come close to realizing who it depicted, whereas 90% of folks looking at a parade of pumpkins would just dart their eyes between the lot till they found the instantly memorable depictions, (it's a small timeframe passers by spent viewing over here anyway don't you think)?
For instance, my money obsessed neighbours kid (spoilt with pocket money) didn't know who the lady was on 50% of the faceings of any uk sterling coins
