Hey 
I like that you are going with the eyes
PP1 helmet is among my favourite Boba variants. And the eyes have a cool backstorie, too! (Like almost everything except the RotJ / ESB costum changes, right [USER=14250]jhfagan[/USER] ?
)
In Universe they are called "jai'galaar'la sur'haii'se" in Mando'a. Or Jaig eyes for short. Means "the eyes of the shreik-hawk". Its a Mando honor mark. 
As far as the variants here go... Don't have a favourite apart from that I don't like "ears" that much
