/cgl/ - Cosplay & EGL

So in my bedroom and kitchen there are two huge skylights that give me natural light since my apartment doesn't have any windows in those rooms. I'll take pics when I get home, but does anybody have any recommendations on how to make them look nicer? They're sealed shut so I can't open them to clean the glass, and they just look gross. I've taped some old theatre posters to cover up the panels in my bedroom, but it doesn't look very nice t b h. Any examples or suggestions are most welcome, I don't want to completely black out the windows since they provide a lot of light but covering up the dirt in an aesthetically pleasing way would be nice.

Pic related except my ceiling is a bit higher, the window is a little smaller, and has three panels.
