Nice KOTOR Darth Nihilus.
I'd give the front drape of fabric beneath your chin a slight tug in order to keep the sides of your hood straight. Only in application pictures as the hood is fine. The cat ears and shape of the head are very good.
The tunics and cape look good. Gloves are great. The boots look good, too. The obi is good.
The skirt is alright. Personally, I would prefer more gathers. From the CRL "The skirt is made with enough material to create a gathered effect around the body." It looks like your tunic and skirt are one piece, though, and so that may not be possible.
Your under-mask... does it cling to your throat? It should. In this particular picture, the throat looks a tad bulged.
From what I'm seeing, this costume is looking really good.
