I think it's a cracking idea, Malc.
This is a subject that's gone around and around, with no definitive answer, as it's all down to personal choice. You look at a miniature person and instantly know whether it's right or wrong. What are the parameters? What exactly is not quite right? Can it be altered, just that little tweak to get it right.
Take my example of the one penny figures from China. It's all down the wrong colours and sizes of the people's heads. (my opinion!)
Good subject for a thread of it's own, Martin.
