Sorry, I don't think they will marry well together. I think your new light fixture is a nice choice, it will pop against your cabinetry where your present one gets lost in it. I notice that your current fixtures in the kitchen are opaque, you are considering the clear glass for a replacement. Are you okay with the glare?

You can mix metals but unless you're highly talented you probably want to stick to two metals. If the metals are different, you want something to tie the two fixtures together. What is your hardware? Is it black? You could do a black and brass light for your pendant lighting.

You have to clean the lens of your camera so we can see.

The conflicting styles aren’t great and since you have ordered the pendants I’d be trying to complement them.

If you want to inject brass and pendants can be returned, maybe go that route and consider slightly more modern for both.

Consider a linear chandelier for balance with your long table and again, aim for similar feels.

Appreciate your ideas and agree. We just ordered a linear style that I think will look great with our pendants. Ty!
