That is Halloween related crossover in support of the contest in our Ahsoka Fan-club. I present it like 'symbolic' out-of-competition exemplary entry cuz I'm one of this contest holders. So I did it just for the lulz.
You can think that this is some kind of Ahsoka's Dark side image but I need to say that these yellow eyes, bitchy-witchy look and other make-up are fully Morrigan's features. And Ahsoka is using *not only*Sith Force lighting at the same time with Yoda's lightings utilizer 'energy ball' (seen in Episode 2 and Episode 3).
I can't say much new about the creation process but this time I used 3 different sources of light and spent some time for understanding and reproducing canonical appearance of Star Wars Force lighting and this 'energy ball'.
