Hi all! I'm wondering: Would this clamshell sconce from Rejuvenation (5-1/8" across) work above a 28" round mirror or would it seem too small? Due to wall space and wiring limitations, we don't have the option to mount lighting on either side of the mirror and I'm not crazy about the look of bar lights.

I love the look of the sconce above the round mirror in this bathroom, but not knowing the size of the mirror in the photo, it's hard to assess whether the proportions would be the same. Thanks for any feedback!
