Well, that fixture over the mirror is way overboard. I cannot tell for sure from the photo but that is wall mounted right? I think some fixture much simpler, and certainly not as "loud" as those orange things, is called for to show off the woodwork. I have seen really nice, low profile, polished metal or frosted glass tube or wand lites with LED arrays. They give off nice light over mirrors and vanities but almost disappear. In short, I think you have enough going on decoratively with the faucets that you don't need a hokey light fixture.
The light in the ceiling over the toilet looks awfully cool. My guess is it is a compact flourescent bulb? I would switch that out to something daylight and with a full spectrum color rendering index.
Is there a bath and shower or is this a half bath? I would switch out the bulb in there to match what you put over the toilet.
