A film director, mentally driven to the edge, fires his ego-maniacal narrator, a pixy, who later manipulates his movie for her own personal gain. — or so it would seem.

I really like this. I was captivated by the concept, the twist and the archetypal characters. I got a bit confused when I got to the "or so it would seem" but without that it's a very strange but interesting and clear line.

I like it.
Who is the protagonist the Director or the pixie? (if you took away "or so it would seem" at the end, the pixie would def come across at the antagonist) or it could just be me ><
I think it's a little busy, maybe shorten it down a little, re word it maybe, see what you come up with.

best of luck.
