I agree remove it or get an electric one but really fake fireplaces are just plain weird and that molding at the ceiling is very ornate , what is your style?

Unless you love it, I would focus all my efforts on removing it, rather than painting it.

You’ve done a marvelous job!

I am surprised at how good you made it look, and with your furniture and the chandelier, it looks really cool and updated (in a fun and funky way).
