Lion-O sculpt, why so hard to make?

I have to be honest, Ive never seen a Lion-O figure or statue that I like, simply because they always get the likeness wrong. Take the new stactions for example, and the ljn figure (Lion-O is the most unaccurate of the line). Why is it so hard to make a Lion-O fig that looks like the cartoon? Is it the hair? Its becoming a frustrating thing for me. The ONLY sculpt Ive ever been satisfied with is this model made by a fellow member of the forums:
