what the title says. as it stands (iirc) only humans & cyborgs can have evil yellow sithy eyes from the start on the character creator. i was trying to make a darth talon clone (basically a twi'lek sith stripper) and the one thing i was missing was her eyes, now to keep her looking like talon i had to keep the ds transition off, as not only do they usually look ugly, it makes her not look like darth talon. so, i see no reason not to add the yellow sithy eyes to every race.

The other problem for making a Talon-like is that not only are the marking/tattoo patterns on the face/lekku wrong for Talon, but SWTOR Twi'leks(1) don't have body tattoos/markings, and Talon very much does.

 

(1) And any other species. Other MMORPGs that I've played that have tattoos/markings have them for both head and body, usually selectable separately.
