There are default proportions, and then there is reality and the variances we see in everyday life.

Take this picture of Cher, chosen because one of the V4 characters resembles her.

By my observations, her eyes are too big, her mouth is too large, and her face is too long.. BUT she's a real person, and is quite beautiful. so how can ideal proportions apply?

When a figure is released, options are adjusted for the most popular idealized look.. yes you can scale things up or down, but the creators just chose to make V4 their own ideal.... but that's WHY they build all those dials in, people! LOL!

Way too many people take way too many things way too seriously.
