I'd say that you've caught her "look" just right. I read the original Timothy Zahn books that introduced Mara back in the day, and I got a very clear image in my head of how she appeared from her speech and her actions... and this render is maybe 97% of what I imagined.

I also agree with you on the "generic pretty" issue. It's a forgettable sort of appearance for a character that had such an impact...
