Tayler's+Mask+Project

For my Mask Project, I want to reflect it off my dream job Astrophotography/Astronomy. Im going to paint my mask a dark blue/purple to be the atmosphere. I'll take a sharp object and poke holes of different sizes through my mask. Therefore when i put a light underneath it will shine like the stars. It will be inclosed in a box. the bottom and side will be a mirror and the rest except one clear piece will be a black sides. My problem is the lighting maybe being to bright and taking to effect away from it.
