Looks fantastic. Amazing job!

Also a huge fire hazard, don’t do this.

If this is the ceiling and a small room I would put a utility ceiling in. Where I live for a room like a simple washing room that would be 150 euros tops and you can always run new wires and get to the old ones without hassle. Nothing else will make it look pretty.

Dont doubt it. You did a great job.

This looks great imo. Why do you doubt that?
