Moroccan-influenced architecture was very popular in the US in the 1920s, the same era in which Art Deco became popular. You may want to consider Art Deco styles for your over-mirror lighting.

I like your lights with the wall paper. They look like fruits hanging down. I would go with a simpler mirror with some aspect of delicacy. something like this (you can find much cheaper versions than this)

Yes your mirror selection is too small & the frame is too pinkish.

Thanks, everyone! So, what vanity light style should I go with assuming I get a larger Moroccan/Art Deco style mirror?

I’d tape out the size, as it looks like your mirror is not centered over sink and mirror should be higher. Choose the light after you place the mirror. It’s important to consider faucet/mirror/light coordination and suggest brushed silver/nickel - keep it simple and elegant due to the busy paper.

If by "moroccan" you mean narrow fretted arches at the top and a wider flat bottom try uplights -- including try to turn your current vanity lights up.

Thanks everyone! The mirror did seem a bit short to me but I was so focused on replacing the light. I’ve ordered this mirror and this light. Fingers crossed these will look good together! Note: I’ll be replacing the faucet soon too!

(yeah, sorry nobody read "brushed brass" in your original post!)
