The scalloped one doesnt work with the others. I would bring in a solid metal that matches the metal on the others and keep it simple. Too much going on , on repeat can look caotic.

I think you're on the right track. The fixtures don't need to match perfectly, but they should share a common design language—similar finishes, proportions, or overall style. That usually creates a more curated look than buying an identical collection.

I recently compared eight very different designer-inspired lights side by side in real interiors. It may give you some additional ideas for mixing statement lighting without making the space feel random.
