Lazz, they are beautifull. One of your best project.
Only in the blue/violet one the two ears joining at the center of the photo look not so nice to me.
But this may come from my general dislike to ear appearing in a face's image. In my elaborations never there are ears, maybe in some isolated exceptions but I don't rebember one.
Have the best compliments and good luck for when showing them. Let's know how it went.
Ciao
