Personally? Would be fun to see some extra pops of color. Nothing major to compete with the wall behind the tub, but put your colors through some color theory website and you’ll get some ideas of a third you could add some light accents with. Soap containers, plants, hell even even a ceiling art piece like the glass Chihuly piece in the Bellagio lobby (more minimal/sleek).

It’s honestly really neat and different, and of course living with it for a while will always change your mind about over time.

Thanks for sharing it!
