This looks real good.
Actually, I tried to do this myself, but without the darkside transitions, and only a female Twi'lek. I liked the end result, a bit, but 'tis nothing compared to this.
Have you made these textures from scratch? They do look like it.
If they are, they're very well done.
Nevertheless, this is a mod to look forward to.
Personally, I prefer the male Twi'lek's darkside transitions more than the female's. Don't know why, but they seem more natural.
The Rodian is a real nice thing too, godd work.
