Hello, welcome to GH where I am officially the pickiest GM ever.
I like your power, however I have some irks:
1. There's a lot going on, lots of possible things with 'light manipulation'.
2. Your limitations seem ok, but how about 'practice'? Since he has to make an image for an illusion... it wouldn't be perfect the first time? Maybe.
I would recommend changing the power to Light Illusions - making holograph-like images from light.
