Quote - The Metropolitan London head is a bit too young looking for the rest of the body.  Maybe fine for alien use.

Your Post made me think of Heavy Metal Magazine.
Heavy Metal Magazine one of the first if not the first adult graphic novels in the U.S.
There is or was a European version of Heavy Metal.
I think before the U.S.Heavy Metal.
Paolo Eleuteri Serpieri's Druuna. One of the most famous SciFi adult graphic novelist.
Lusi Royo One of the most famous Artist that can make balanced young laddies.
Royo's girls don't look like a young face on a mismatched body.
Don't know if Royo started the young face characters but since he's so famous.
Every one copy's what the famous one's do.

A lot of the best Artist have been associated with Heavy Metal.
A lot of what Artist learned is from Heavy Metal.
Heavy Metal's been around since before home PC's.

There's a lot of ratios to consider when making characters.
DAZ adult Characters always have a hug body and small head so they seem older.

The Artist that will fight for decades to conquer their media.
Even if you never know their name ,your know their Art.
